Electrolysis is the only proven method of PERMANENT hair removal. Shaving, tweezing, threading, waxing and laser treatments only offer "temporary" results. Electrolysis was first developed in 1875 by an eye surgeon in an attempt to find a method to relieve his patients from ingrown eyelashes. He found the method (called electrolysis) not only removed the offending hair; but, it didn't grow back. Thus was born the science of electrolysis. A slight amount of electric current is applied through a small probe eliminates the hair's source of nourishment.
All other removal methods are temporary. Tweezing, waxing, and threading only rip the hair out. The hair is just replaced by another hair. Shaving and depilatories remove the hair at the surface of the skin level and the hair continues to march on out.
Laser hair removal is not capable of treating white, gray, or light blond hairs. They have insufficient pigment to attract laser light. Also, red hair is in the red spectrum of light which the laser utilizes. Therefore, laser light will not detect red hairs. Laser manufacturers are not given permission to claim "permanent" hair removal by the Federal Government's Food & Drug Administration (FDA). This means that although laser treatments may reduce the number of body hairs, they will not result in "permanent" removal.
Electrolysis is the only answer for permanent hair removal. It is the only removal method recognized as permanent by the American Medical Association and the Federal Food and Drug Administration (FDA).
