Abstract

The invention disclosed provides a method of depilation in human mammal by injecting a dose of chemical depilatory solution into hair follicle such to permanently destroy hair growth at that location. Injection of the chemical depilatory solution may be effected by means of a hypodermic syringe for penetrating beneath the skin surface and for dispensing effective dosage amounts of the depilatory solution into the follicle.

Claims

1. A method of permanently destroying hair growth within a hair follicle of a living mammal comprising the steps of inserting the needle end of a hypodermic syringe to disperse a minute dosage of chemical depilatory solution non-toxic to the biological system beneath the skin into the follicle alongside the hair to be destroyed, dispensing said chemical depilatory solution within the haiR follicle to reach the vicinity of the papilla, and withdrawing said needle immediately after dispensing said solution.

2. The method as defined in claim 1, wherein in said insertion step the needle end of said hypodermic syringe is inserted to a depth of about 3 to 4 mm. within said hair follicle.

3. The method as defined in claim 2, wherein in said insertion step the needle end of said hypodermic syringe enters the region of the papilla.

4. A method of depilation in human mammal comprising the steps of, choosing as a dose a controlled amount of a selectively acting depilatory chemical solution non-toxic to the biological system of the mammal for adequately reacting with the hair forming structure to destroy it, injecting the dose of depilatory solution into the hair follicle beneath the skin surface, and permitting said solution to remain in the follicle until the chemical reaction with the hair forming structure is completed, the controlled quantity thereby limiting the possibility of inflammation.

5. The method defined in claim 4, wherein the solution is a soda solution.

6. The method defined in claim 4, wherein the solution is a chemical that reacts with Keratin.

7. The method defined in claim 4, wherein the depth of insertion is controlled and the solution is metered in amount and strength to effect chemical reaction only in a limited region about the papilla.

8. The method defined in claim 4, wherein the solution is about 0.01 N to about 0.10 N sodium hydroxide solution.

9. The method defined in claim 4 wherein the amount of solution injected is about 1 to about 5 microliters.
