Unwanted hair removal

When you have made the decision to rid yourself of unwanted hairs there are two choices to consider electrolysis and laser. As with electrolysis, cases of scarring have been reported, but these are extremely rare. Compared with electrolysis, laser hair removal is more precise and much faster. Electrolysis is intended to be a permanent hair procedure, but much like laser hair removal, it is not guaranteed to be 100% effective. Prior to laser technology, the only options for removing unwanted hair were smelly hair removal creams, sharp razors, stinging wax or painful electrolysis needles. In fact, laser technology is already eliminating the need for these traditional methods.

Almost anybody who has undesirable hair is a candidate for laser hair removal. Both men and women have found laser technology beneficial for hair removal. A common area where laser hair removal is used is the face, chin, and upper lip on women. Another area to receive laser hair removal for women is the legs.

For laser hair removal to work, the light energy is selectively absorbed by highly pigmented hair fibers and hair follicles. So, less laser energy is required to remove upper lip hair than for pubic hair. Several wavelengths of laser energy have been used for hair removal, from visible light to near infrared radiation. In facial hair removal, a low energy laser beam is directed towards a group of hair follicles.

Current laser hair removal techniques use wavelengths of light that target melanin, the pigment that determines color of both hair and skin. The level of pain depends on the patient and the person's skin and hair type. The presence of a suntan makes hair removal less effective and increases the likelihood of scarring or skin injury. As such, skin color must be taken into consideration. The risks can include skin discoloration, swelling, and infection. Generally, patients with dark hairs and fair skin respond best to laser hair removal.
