What It Is : The only method of hair removal that is permitted to be called "permanent," electrolysis uses a tiny needle that slides down into the hair follicle until it reaches the cells responsible for hair growth.

"Electrolysis destroys the cells that cause the hair to grow. The hair will release and slide right out and it won't grow back there again -- it's permanent removal," says Patsy Kirby, executive director of the American Electrology Association in Bodega Bay, Calif.

The process can be uncomfortable, but local anesthetic creams can help.

Best For : Like other forms of hair removal, it is safe to do electrolysis anywhere on the body, though Kirby says the most popular place for women is the face.

How Long It Takes : Though the system requires that the removal be done hair-by-hair, Kirby says it's not as daunting a task as it might seem. "It can take up to 25 sessions, depending on how much you need removed, but each session may only be 5 or 10 minutes long," says Kirby.

Cost: Costs run between $40 and $90 per treatment, with 10 to 25 treatments (or more) sometimes necessary for permanent, lasting results.

Potential Drawback : Electrolysis can cause tiny scars where the needle is inserted. Though for most people they heal unnoticed, for blacks it means an increased risk of hyperpigmentation and formation of keloids. Thus, it's not recommended for this skin type.
