Abstract
Hair is removed from the body and future growth is inhibited by treating the outer surface of the hair so as to reduce RF energy dissipation and permit more RF energy to reach the hair root and thereby damage or destroy the same. The hair is treated with a conductive material such as a conductive metal, a conductive solution such as a metal salt, an acid, or a base.
Claims22
The method of removing a hair from a skin surface of an individual and inhibiting future growth by causing said hair to be sufficiently damaged at its root so as to be more readily releasable at its root and removable by a very gentle force rather than the normal force required to pluck a non-treated hair from the skin surface, comprising the steps of:
- a) treating the outer surface of the hair which has a longitudinally extending inner central core to reduce RF resistance between the outer hair surface and said inner central core of the hair to permit more RF energy during an entire treatment time to enter the inner central core and travel therealong within the hair interior to reach the hair root;
- b) firmly grasping the hair between a pair of opposed RF insulated hair engaging surfaces at a point relatively close to but clear of and above the skin surface of the grasped hair;
- c) applying RF energy to at least said one of said hair engaging surfaces;
- d) holding said hair engaging surfaces in firm engagement with said hair while applying focussed RF energy to said hair for a period of time sufficient to cause the RF energy to travel across the hair and into the inner core of the hair and to damage the hair root sufficiently to permit the hair to be removed by a very gentle upward lift;
- e) applying a gentle upward lift to the hair by the hair engaging surfaces during application of said RF energy, without exerting the tug ordinarily required for removal of non-treated hair.
The method of removing hair from a skin surface of the body of an individual and inhibiting future growth to cause said hair to be sufficiently damaged at its root so as to be releasable at its root and removed by a very gentle force rather than normal force required to pluck a non-treated hair from the body, comprising the steps of:
- a) treating the cuticle of a hair having a longitudinally extending inner central core to cause the hair to absorb an RF energy conductive material to thereby reduce RF resistance between the outer surface and the inner central core of the hair during an entire period of RF application and to thereby reduce RF energy losses and permit more RF energy to travel down the core to reach the hair root;
- b) firmly grasping the hair between a pair of opposed RF insulated hair engaging surfaces at a point relatively close to but clear of and above the skin surface, at least one of the hair engaging surfaces being capable of emitting focussed RF energy to said grasped hair;
- c) applying RF energy to at least one of said hair engaging surfaces;
- d) holding said hair engaging surfaces in firm engagement with said hair while applying RF energy to said hair for a period of time sufficient to cause the RF energy to travel into the inner core of said hair and along the core to said hair root to cause said hair at said root to be damaged sufficiently to inhibit future growth;
- e) sensing when there is sufficient damage to said hair root to permit ready release of said hair from said skin surface by applying a gentle upward pull by said hair engaging surfaces away from said skin surface during application of said RF energy without requiring the normal tug required to pull a nontreated hair;
- and,
- f) completely removing said treated hair from said skin surface by continuing the gentle upward movement away from said skin surface by said hair engaging surfaces.
