There are three types of hairs on your skin:
Human hairs
Vellus: sometimes called "peach fuzz," these are soft, tiny, colorless
hairs found on the face and body (often,no medulla). Sensitive to
hormone-related conditions and become thicker, darker and coarser
resulting in terminal hair.
By type
*Vellus hair
*Terminal hair
*Lanugo ( Infant only)
Intermediate: hairs between vellus and terminal. Thin, but with some
pigmentation.
Terminal: these are deep-rooted, thick, coarse hairs, either
pigmented or gray. Found on the scalp,underarms,pubic
region,eyelashes and eyebrows. In men, presented on the chest and
beard areas. (usually the hairs consumers want removed).

Reasons for removing hair
*Ingrowing hairs
Hairs which have not grown above the skin surface and are still in
the follicles.if lefted, the hairs can become infected.
*Embedded hairs
1.Medical reasons:
-In Ancient Egypt, many people depilated
their entire bodies to prevent infestation by lice,
fleas, and other parasites. Ancient Egyptian priests
also shaved or depilated all over daily, so as to
present a 'pure' body before the images of the
gods
Hairs which have become trapped below the skin.
*Pili Multigemini hairs
Two or more hairs grow out of a single follicle.
*Corkscrew hairs
The hair is curved due to the follicle being distorted in shape.
Over treatment using temporary or permanent hair removal methods
can cause this condition.
-Patients' body hair was once shaved before
surgery for reasons of hygiene
รศ.พิมพร ลีลาพรพิสิฐ
รศ.พิมพร ลีลาพรพิสิฐ
3.For religious reasons:
2.Social, cultural, or sexual reasons:
-Many men in Western cultures shave their facial hair, so
only a minority of men have a beard, even though fast-growing
facial hair must be shaved daily to achieve a clean-shaven or
hairless look
-Some men shave because their beards are very coarse,
causing itchiness and irritation. Some men grow a beard from
time to time to change their appearance
-In many cultures, particularly North American and
Western European, it became increasingly common during the
20th century for women to remove some or all of their body hair,
due to societal values that consider it unattractive and/or not
feminine , or as a matter of practising good hygiene. People may
also remove some or all of their pubic hair for aesthetic or sexual
reasons
รศ.พิมพร ลีลาพรพิสิฐ
-Head-shaving is a part of some Buddhist, Christian,
Muslim, Jain and Hindu traditions. Buddhist and Christian
monks generally undergo some form of head-shaving during
their ordination; in Thailand monks shave their eyebrows as
well. Brahmin children have their heads ritualistically shaved
before beginning school.
-In some parts of the Theravada Buddhist world, it is
common practice to shave the heads of children. Weak or
sickly children are often left with a small topknot of hair, to
gauge their health and mark them for special treatment.
When health improves, the lock is cut off.
-Muslim law (Sharia) puts hair in three categories: that
which it is recommended to remove (pubic and armpit hair),
that which it is recommended to keep (the beard), and that
which is the object of limited recommendation (foot, hand,
back, and chest hair). Removal of armpit and pubic hair is a
hygienic practice which was taught by Muhammad and
which was enumerated as having been part of practices
conforming to man's premortal (Fitrah) nature

Body areas where hair is often removed
4.As punishment:
Hair grows on all areas of the human
body except for the palms of the hands,
the lips, certain areas of the genital
structure and the soles of the feet. But
hair is most noticeable in most people in a
small number of areas that are most
commonly waxed, trimmed, plucked, or
shaved.
-In some situations, people's hair is shaved as a
punishment. Before World War II, the Nazis would cut off the
beards of Jews as a prelude to other forms of abuse.
-After World War II, head-shaving was a common
punishment in France, The Netherlands, and Norway for
women who had collaborated with the Nazis during the
occupation, and, in particular, for women who had
"collaborated" sexually.
-During the Vietnam War, conservative students would
sometimes attack student radicals or "hippies" by shaving
beards or cutting long hair..
-In Arab countries, shaving off head-hair is sometimes
used to shame and humiliate male prisoners.

Epilation (removing the entire hair).
Less common method of removing hair at skin's surface, but
primarily useful for fine hair on legs.
Epilation lasting several days to several weeks
Description:
A rough surface is used to buff away hair at the skin's surface.
usually has rough strips or a smoothing surface coated
directly onto the mitt.

*Tweezing (Plucking)
*Waxing (a hot or cold layer is applied and then removed with porous strips)
Advantages:
Inexpensive, fast, essentially painless, also exfoliates and
smooths skin.
*Sugaring (similar to waxing, but with a sticky paste)
*Threading (also called fatlah or khite, in which a twisted thread catches hairs
as it's rolled across the skin)
Many types can be used wet or dry.
Good for legs with fine hair.
Some use it between shaving or waxing sessions.

Permanent Methods
"Permanent" Methods
Permanent hair removal involves several
imperfect options. A number of methods have been
developed that use chemicals, energy of varying
types, or a combination to target the areas that
regulate hair growth. Permanently destroying these
areas while sparing surrounding tissue is a difficult
challenge. Methods include:
*Electrolysis
*Laser
*Intense Pulsed Light (Flashlamp, EpiLight) The

Permanent hair removal
รศ.พิมพร ลีลาพรพิสิฐ
Basic facts:
Electrolysis
For the purposes of hair removal, the hairfacts definition of
"permanent" is being able to go a year after final hair removal
treatment without having to use another method of hair removal.
Permanent hair removal for most consumers if
performed correctly (which requires considerable training
and skill).
Keep in mind that a year might not be long enough to
determine true permanence, but most consumers would be happy to
have one treatment a year.
Description:
The only method of clinically proven permanent hair
removal is electrolysis.
Some lasers and flash lamps have been able to achieve permanent
hair reduction.
A hair-thin metal probe is slid into a hair follicle.
Proper insertion does not puncture the skin.
Electricity is delivered to the follicle through the probe,
which causes localized damage to the areas that generate
hairs.
performing electrolysis on yourself is very difficult
and not recommended

1.Galvanic electrolysis: works by causing salt and water in the
skin around the probe to be chemically altered to produce a small
amount of sodium hydroxide, or lye.
Lye is the active ingredient in some crystal drain openers. If enough is
produced, it can damage the cells that cause hair growth.
The chemical reaction is expressed like this:
NaCl (salt) + H2O (water) + direct current = NaOH (sodium hydroxide) + Cl
(chlorine) + H (hydrogen)
2.Thermolysis electrolysis: works by causing water molecules
in the skin around the probe to vibrate, which creates heat. If enough
heat is produced, it can damage the cells that cause hair growth.
3.Blend:
is based on the theory that lye is more caustic when
heated. Theoretically, blend is more effective than other methods if
performed correctly.
Blend is recommended by several experts but electrologist skill is
by far the most important factor in safe and effective treatment.
รศ.พิมพร ลีลาพรพิสิฐ
รศ.พิมพร ลีลาพรพิสิฐ
Subsequent innovations in the field included the use of
multiple needles, and the use of AC electricity, which causes thermal
damage within the follicle This method was called Diathermy
and is also called thermolysis, short-wave, high-frequency (HF), radiofrequency (RF), etc.
Galvanic electrolysis
Clinical data:
Two well-designed Japanese studies demonstrate permanence
in treating underamrs.
The thermolysis study showed "little to no regrowth" at 6 to 36
months after
3 to 8 treatments to the underarm.
The blend study observed no regrowth at 6 months after 7 to 14
treatments, while comparative plucking resulted in no significant hair
removal at
6 months.

"Permanent hair reduction"
Hair reduction vs. hair removal
In
1998, the US Food and Drug Administration (FDA) began allowing
Permanent hair removal has been established as the
complete destruction of a hair follicle's ability to regenerate and
grow hair.
some manufacturers of hair removal lasers and flash lamps used for
epilation to use the term "permanent hair reduction," which the agency
defines as:
Several lasers have demonstrated permanent hair reduction
in clinical studies and are allowed to make this claim by FDA.
The long-term, stable reduction in the number of hairs regrowing
after a treatment regime. The number of hairs regrowing must be stable
over a time greater than the duration of the complete growth cycle of hair
follicles, which varies from 4-12 months according to body location.
Permanent hair reduction does not necessarily imply the elimination
of all hairs in the treatment area.
The word "reduction" adds another term that is vaguely
defined. FDA has accepted the definition of reduction as a stable
reduction in the number of coarse dark hairs.
Some lasers have demonstrated in clinical testing that they
can reduce the size of hairs and lighten the color. In some patients,
this reduction appears to be permanent.

How does laser remove hair?
Epidermal cooling:
- gel
- water cool (glass/sapphire)
- cryogen spray
End point: “perifollicular erythema”
Highly controlled flashes of laser beams are selectively
absorbed by hair follicles lying below the surface of the skin. The
absorbed light heats the hair, which damages and destroys
the regrowth potential of the follicle- all without damaging
surrounding tissue. Hair follicles are usually in different growth
cycles at different times in relation to one another. Since the
follicle must in active growth in order to be affected by the
laser, several treatments spread over several months are
required to assure the destruction of all hair follicles.

Is laser hair removal safe for all skin types?
What happens during a treatment?
It begins by trimming away the hair above the skin. You may be asked to
wear dark glasses to protect your eyes from the bright light. Next, a cold gel is
spread over the treatment area. The laser handpiece is then applied to your
skin and pulses of laser begin disabling your unwanted hair. When the gel is
removed, much of the hair is wiped off with it. The remaining hair in the
treated area falls out over the next week or two.
Cosmetic Laser Center of Los Angeles uses the most advanced
laser systems which are FDA approved for permanent reduction of
hair in all skin types, including dark skinned African Americans
and Hispanics.
What does the treatment feel like?
Each pulse of laser feels like a slight sting or pinch, similar to the snap of a
rubber band. Topical anesthetics may be used but most people don’t require
it.
Can all hair be treated?
Our state of the art lasers offer you customized treatment according to
your hair color, texture and body location. Any hair with at least some pigment
in it (black, brown, red and even blond) can be treated effectively.
รศ.พิมพร ลีลาพรพิสิฐ
รศ.พิมพร ลีลาพรพิสิฐ
Are there any possible side effects?
What kind of results should expect?
Side effects are rare. You may experience some
slight reddening or local swelling at the treatment site, but
this typically goes away within hours. On rare occasions,
some blistering or bruising may occur, but typically
resolves quickly. The skin may also become lighter or
darker following treatment, but will generally return to
normal within a few weeks. Limiting sun exposure
before and after treatments will minimize risk of
complications.
Lasers are FDA approved for permanent hair
reduction. The number of treatments required depends on
several factors related to your specific kind of hair and skin.
Usually five to six treatments spread out 8 weeks apart are
required to achieve satisfactory results. Following each
treatment, you can generally return to work and resume all
regular activities

Semi-permanent hair removal
Long-term hair removal
A newer term used by some hair removal marketers is "semipermanent hair removal."
Another undefined term is "long-term" hair removal. Again, it
depends on what your definition of "long" is.
This is a marketing term used in the salon industry

Electric tweezers
Basic facts:
Electric tweezers and treatments with them should be avoided by
all consumers. They're often promoted as permanent, but facts
indicate otherwise.
Description:
Electric current is applied to a hair through an electrified tweezer.
The tweezer grasps the hair above the skin's surface and holds it
15
anywhere from
seconds to several minutes.
Promoters claim (without adequate proof) that the electricity travels
down the hair and permanently damages the hair root.
Accessories: Some brands sell items like conductive gels,
humidifiers, or pre- and post-treatment products to "increase
effectiveness
Electric tweezer marketers sometimes claim there is a
difference between electric tweezers using alternating current (AC)
and direct current (DC), but there is no published proof indicating
any difference in effectiveness between the two types.
:
General marketing terms no-needle electrolysis, non-invasive
electrolysis, tweezer electrolysis, tweezolysis.
AC tweezers are also marketed as radio-frequency (RF) tweezers,
high-frequency (HF) tweezers, ultrasonic tweezers.
DC tweezers are also marketed as galvanic tweezers.
In 1998 the U.S. Food and Drug Administration (FDA) stated that
"there is no statistically significant scientific data available at this
time to support promotional claims of permanent or long-term
removal of hair through use of the device."

4 Tips to Treat and Avoid Ingrown Hairs
From Daniel Billett,
A variety of staph infection, known as "community-acquired
methicillin-resistant Staphylococcus aureus" (MRSA), was
identified following an outbreak among gay men in Los Angeles in
2003. Among the risk factors for transmission of the infection
identified by the Centers for Disease Control and Prevention is
"compromised skin integrity."
Researchers with the Connecticut Department of Public
Health determined that "manscaping" (hair removal, especially
performed with a dry safety razor and powder) could produce
micro-abrasions of the skin, compromising its integrity.
Men who manscaped were six times more likely to contract
the disease. This drug-resistant strain of S. aureus has been
found prevalently among gay and bisexual men, athletes,
prisoners and Native Americans.
รศ.พิมพร ลีลาพรพิสิฐ
Avoid Unsightly and Painful Ingrown Hairs
Ingrown hairs (also called razor bumps) are unsightly and painful.
They result when the shaved hair gets trapped inside the follicle or
grows back into the skin. It can cause scarring, redness and swelling
(its medical term is Pseudofolliculitis Barbae or PFB).
1. Treat with active ingredients
-Salicylic acid is the one active substance that can visibly
improve razor bumps. It is a dermatological-grade ingredient that
exfoliates, moisturizes, clears pores and can help prevent infection
-Use a post-shave product with salicylic acid
-Use only a non-acnegenic shaving cream specially
formulated for sensitive skin, with lots of lubricating agents (foambased shaving creams can dry and irritate your skin).
-Do not use any product that has alcohol, it will seriously
worsen ingrown hairs by drying the skin and closing the pores.
รศ.พิมพร ลีลาพรพิสิฐ

2. Improve your skin's surface
-Exfoliating (removing the upper layers of dead skin) is
indispensable to manage ingrown hairs.
-Daily use of a gentle face scrub with glycolic and salicylic acid is
particularly effective.
-Use a soft-bristle face brush and liquid cleanser in a circular
motion on your beard to dislodge the tips of ingrown hairs, eliminate
dead skin cells and clear follicles to allow hairs to surface unimpeded.
3. Adjust your shaving technique
-Shaving too closely is one of the triggers for razor bumps..
-To avoid shaving too close, don't pull the skin when you shave;
don't put too much pressure on the blades; shave with the grain and
use a single-blade razor.
4.Treat already ingrown hairs
-Carefully lift the ingrown end out with tweezers, but don't pluck
the hair out; this will only make the hair regrow deeper.
Using products that contain azulene, allantoin and
witch hazel will help reduce the redness and swelling.
Facial Hair Removal
Almost all parts of the body have hair including the
face. Hair on the face is particularly annoying to
women. It may make them feel unfeminine,
unattractive, cause stress and loss of confidence. It is
normal for the face to have fine downy hair. When this
hair growth is coarse and thick, the problems start. This
excessive hair growth may be due to hereditary
factors, hormonal imbalances or as a reaction to
certain medicines.
The various methods used to remove facial hair are
detailed below. The method chosen will depend upon
the intensity of the hair growth, the concentration of
the hair growth and the will and desire of the
women concerned.
รศ.พิมพร ลีลาพรพิสิฐ
รศ.พิมพร ลีลาพรพิสิฐ
1.Bleaching
Bleaching is a common method of disguising and
camouflaging facial hair. A peroxide solution is used to
lighten the color of the facial hair. As this is a chemical
process, it is important to take due precautions and pre
testing is advised strongly. If this is done wrongly, it may
leave burn marks on the face.
2. Plucking
Plucking of facial hair with tweezers is suitable
for removing isolated hairs on the chin or between the
brows. It is important to remember to disinfect the
tweezers and the area of the skin to be plucked before the
start of the process. This can be done with a a mild
astringent or a antiseptic liquid. It is not advisable to
pluck hair growing from a mole or hair on the upper lip.
3. Threading:
-Threading can be used for shaping
eyebrows and for removing fine hair from the
face and the area above the upper lip and along
the hair line.
-To avoid skin irritation and redness, it is
recommended that a little zinc ointment be applied
after the process.
-Threading should normally be avoided in
conditions of acne as it can cause the problem
to intensify and spread.

4. Electrolysis
รศ.พิมพร ลีลาพรพิสิฐ
5. Laser Hair Removal
If the facial hair is dark and coarse and a
source of major embarrassment, a lady may look at the
option of electrolysis. The diathermy method is
quite popular. In this method an electric current is
passed through a fine needle, which is inserted into the
hair follicle and this cauterizes (burns) the hair root. This
prevents re growth. In the hands of a novice or an
non-professional. this process can cause facial
scarring. Hence, it is most important to take due care
and do a lot of research before settling on this process
as an option. In extreme cases, re growth of hair has
also been known to occur, so it is important to
understand all the pros and cons of the process before
submitting to it.
รศ.พิมพร ลีลาพรพิสิฐ
This new method of hair removal is gaining
importance. However this is not for everyone. One
important requirement is that one's hair should be
darker than the surrounding skin. Lasers can cause
localized damage by selectively heating dark target
matter in the area that causes hair growth while not
heating the rest of the skin. It is cheaper than
electrolysis but depends upon skin and hair tone
and color to be effective. Treatment of skin with
lasers is gaining in popularity but requires great care. It
is very important to understand the treatment,
understand the suitability for the skin type and find the
right place to get it done. It also requires multiple
sittings and has to be done by a professional.

VANIQA – your best choice for facial hair
removal creams
6. Perma Tweeze
This is also a relatively newer method of hair
removal. In this procedure a tweezer, that is
electrically operated, is used to pluck hair from the
root. It also requires multiple sittings. It is
expensive and does not normally carry the risk of
scarring. The texture, and amount of hair growth will
normally decide if this treatment is to be recommended
and if it will be effective.
Using depilatories and creams to remove unwanted hair
is very common practice. There are several known brands for
removing hair in the legs, and arms. The use of these
depilatories is well and good, especially for the legs,
however, using these creams for removing facial hair is not
recommended The depilatories for removing unwanted hair
tend to contain harsh chemicals which may harm the face’s
sensitive skin
Vaniqa is an FDA approved cream and is
recommended by dermatologists for use in removing
unwanted facial hair. It is a cream available through
prescriptions and has been clinically proven to slow the
growth of female facial hair. Vaniqa is a cream that works on
all skin and hair types, removing and reducing the
development of unwanted hair by blocking the enzymes
that cause its growth

Wet shaving
Shaving methods
Shaving can be done with a straight razor or safety
razor (called 'manual shaving' or 'wet shaving') or an electric
razor (called 'dry shaving').
If a manual wet razor is used, some lathering or
lubricating agent such as cream, soap, gel, foam or oil is
normally applied to the area to be shaved first; this helps
avoid a painful razor burn.
These lubricate the area to be shaved, moisturize the
skin and lift, soften and swell the hairs. This enhances the
cutting action and sometimes permits cutting the hairs deeper
Safety razor, shaving brush and shaving soap.
The brush is used to make lather from the soap.
below the surface of the skin
รศ.พิมพร ลีลาพรพิสิฐ
There are two types of manual razors: straight razor and safety
razors. Safety razors are further subdivided into double-edged razors,
injector razors, cartridge razors and disposable razors.
*Straight razors are still made today, Shaving with these razors requires
some practice but one can pick up the art very quickly. Once it was
more commonplace but now is seen mostly in use in barber shops
wielded by a skilled barber.
*Double-edge razors are also readily available and are still made by
Merkur in Germany, Antique Gillette, Wilkinson Sword, Schick, and
Feather (a Japanese company). Double-edge razors are named so
because the blade that they use has two sharp edges.
*Cartridge razors are the most expensive type as the blades are
designed to only fit the razors of the manufacturer. Current multi-bladed
cartridges claim to improve shaving and have seen a design war with
manufacturers adding greater numbers of blades than competitors.
*Disposable razors are the cheapest available and have a simple
handle built into the blade.
รศ.พิมพร ลีลาพรพิสิฐ
Shaving soap or cream
Shaving cream acts as a lubricant and a
moisturizer, and also as an indicator of which areas have
not been shaved.[9] Shaving gels may dry out the skin.
The modern shaving cream may be slightly more
expensive but offers a more comfortable shave; they are
often found to be enriched with aloe vera (soothing) and/or
tea tree oil (natural antiseptic). A cheaper alternative is to
use any soft soap and a brush with long soft bristles
(called a Shaving brush). The soap is worked up into a
foam by the brush, either against the face, in a Shaving
mug, bowl or scuttle.
รศ.พิมพร ลีลาพรพิสิฐ
รศ.พิมพร ลีลาพรพิสิฐ
The electric razor
consists of a set of oscillating
or rotating blades, which are held behind a perforated
metal foil that prevents them coming into contact with the
skin. Bristles poke through holes in the foil and are sliced
by the moving blades. In some designs the blades are a
rotating cylinder, in others they are one or more rotating
disks, and in others a set of oscillating blades. Each
design has an optimum motion over the skin for the best
shave and manufacturers provide guidance on this.
Generally for circular blades it is a circular motion and for
cylindrical or oscillating blades it is up and down. The first
electric razor was built by Jacob Schick in 1928.
Side effects of shaving
Shaving can have numerous side effects, including cuts,
abrasions, and irritation. Many side effects can be minimized
by using a fresh blade, applying plenty of lubrication, and
avoiding pressing down with the razor. A shaving brush can
also help. The cosmetic market in most developed consumer
economies offers many products to reduce these effects;
they commonly dry the affected area, and some also help to
lift out the trapped hair(s). Some shavers choose to use only
single-blade or wire-wrapped blades that shave farther away
from the skin. Others have skin that cannot tolerate razor
shaving at all; they use depilatory shaving powders to
dissolve hair above the skin's surface.
The main disadvantages to electric shaving are that it is
not as close as wet shaving and you need a source of
electricity. The advantages are as follows: fewer cuts in
the skin, no ingrown hairs (pseudofolliculitis barbae, also
called razor bumps), quicker shaving, no need for a water
supply.

Razor burn
Ways to prevent
razor burn include keeping the face
moist, using a shaving brush and lather, using a moisturizing
shaving gel, shaving in the direction of the hair growth,
resisting the urge to shave too closely, applying minimal
pressure, avoiding scratching or irritation after shaving,
avoiding irritating products on the shaved area (colognes,
perfumes, etc.) and using an aftershave cream with aloe vera
or other emollients.[10]
Also, it is good to prepare the skin for shaving by
cleansing the area to be shaved with a face wash containing
salicylic acid, to facilitate the removal of oils and dead skin.
Putting a warm, wet cloth on one's face helps as well, by
softening hairs.[11]
Ways that may help heal and soothe razor burn include
applying witch hazel, mild salicylic acid solutions, aloe vera
gel or cold water.
Razor burn is an irritation of the skin caused by using a
blunt blade or not using proper technique. It appears as a mild
rash 2-4 days after shaving (once hair starts to grow through
sealed skin) and usually disappears after a few hours to a few
days, depending on severity.
In severe cases, razor burn can also be accompanied by
razor bumps, where the area around shaved hairs get raised red
welts or infected pustules. A rash at the time of shaving is
usually a sign of lack of lubrication.
Razor burn is a common problem, especially among those
who shave coarse hairs on areas with sensitive skin like the
bikini line, pubic hair, underarms, chest, and beard. The
condition can be caused by shaving too closely, shaving with a
blunt blade, dry shaving, applying too much pressure when
shaving, shaving too quickly or roughly, or shaving against the
grain.
