					 How Laser Hair Removal Works on Different Skin Types and Hair Color

The effectiveness of laser hair removal is dependent upon several factors
including skin type and hair color. Lesser factors include the condition
of the skin, sun exposure, and the cycle of the hair.

There are four basic skin types - Caucasian European, African descent,
Eastern Asian, and Middle Eastern / Mediterranean. Each of these four
skin types have several things in common, such as the thickness of the
dermis and epidermis, the number of hair follicles, and the skin's
layered components. However, there are many characteristics of each skin
type that are very different.

Caucasian Europeans have the most varied skin type of all the groups.
This group has light skin with great variation in skin color amongst the
people which is determined by heredity. The      people from this group
are the best candidates for laser hair removal. Generally, they will
need fewer treatments and attain the best results. Overall, the
effectiveness of laser hair removal on individuals from this group is
dependent upon a combination of their hair and skin color.

Individuals of African descent, with dark brown skin or poor candidates
for laser hair removal. This is because the laser light is absorbed into
the skin pigment, causing possible burns, scars, and keloids. The dark
skin causes the laser beam to b drawn away from its target area.

People in Eastern Asian descent, which includes China, Japan and Korea,
generally have the least amount of facial and body hair. They are
usually good candidates for laser hair removal because their hair is
dark, and they have minimal skin pigmentation.

Middle Eastern and Mediterranean people tend to have the most facial and
body hair. Their skin color can very from dark white to medium brown.
Those people with lighter skin generally make better candidates for laser
hair removal. Skin bleaching agents, such as 4% hydroquinone, are
sometimes used by people in this group to lighten the skin as much as
possible. This is done to make the laser treatment as effective as
possible and reduce the risk of burning the skin. This ethnic group has
an increased risk of hyperpigmentation.

Hair color combines with skin type to further determine the effects of
laser hair removal. Black or dark brown hair is usually coarser and
contains the most pigmentation. These factors make it the easiest to
treat because the laser light is most easily absorbed by the dark
pigmentation. Lighter brown hair usually requires more treatments than
darker hair. The lighter the hair color, the more difficult laser hair
removal becomes. Red and light blonde hair contain phemelianin pigment
which makes light absorption very difficult. Grey or white hair does not
contain any pigmentation at all, therefor, they cannot absorb light. The
Fitzpatrick Skin Phototype Scale and the Lancer Ethnicity Scale are used
by professional technicians to determine the effectiveness of laser hair
removal based on skin type and hair color.
The best combination of skin type and hair color for laser hair removal
is light skin with dark hair. These people will have the best results
with the least treatments.
