Hair Removal

👤by AP 0 comments 🕔Friday, January 31st, 2014

All hair is dead protein. Hair's superficial appearance depends upon its anatomical location. Fine poorly pigmented hair tends to grow on certain parts of the face like the upper cheeks and forehead. Thick darker hairs grow on the edges of the eyelids and brows, the male jaw-line, the scalp, nostrils, and pubic areas. These characteristics often change as one ages. The palms, soles, and the vermilion of the lips do not have hair or hair follicles.

Laser light is absorbed by pigment in the hair causing the production of heat that can be used to destroy both the hair and adjacent tissues. When done correctly in the appropriate patient, only the follicular tissues are damaged resulting in hairlessness for an extended period of time. The process may have to be repeated several times before there is any permanent result. Those with contrasting light skin color and dark hair are the easiest to treat where as those in whom there is little color difference between skin and hair can be challenging. Those with darker skin often require lasers that generate longer wavelength light. Occasionally, it may be necessary to add an exogenous pigment to the hair if the hair is naturally uncolored. Laser hair removal is relatively expensive and should only be performed by an experienced operator. Laser hair removal can be painful. Poor results are frequently due to darkening of the treated skin and actual thermal burns. There are laser and light systems (Tria, Flash & Go, i-LIGHT Pro) available for use at home by the untrained consumer. Whether this is a safe and effective approach to hair removal remains to be seen.

Vaniqa for Hair Removal

Eflornithine is the first topical drug (used on the skin) for the treatment of unwanted facial and chin hair. It does not remove the hair but rather slows its growth.
