Abstract
Abstract The invention features a method of removing a hair, involving mechanically or chemically removing the hair to expose the follicle of the hair, and then treating the follicle to inhibit its ability to regenerate a hair. Removing the hair facilitates the uptake of a follicle-inactivating compound and thus allows for long-term inhibition of hair growth.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
44 words
A method of removing a hair from the skin of a mammal, the method comprising (a) applying to the hair a chemical agent that removes the hair from its follicle, and then (b) treating the follicle to inhibit its ability to regenerate a hair.
Claim 2
Independent Claim
44 words
A method of removing a hair from the skin of a mammal, the method comprising (a) applying to the hair a chemical agent that removes the hair from its follicle, and then (b) treating the follicle to inhibit its ability to regenerate a hair.
Claim 3
Dependent Claim
15 words
The method of claim 1, wherein the chemical agent breaks disulfide bonds in the hair.
Claim 4
Dependent Claim
15 words
The method of claim 1, wherein step (b) comprises applying a toxin to the follicle.
Claim 5
Dependent Claim
12 words
The method of claim 3, wherein the toxin is an antimetabolic drug.
Claim 6
Dependent Claim
11 words
The method of claim 4, wherein the antimetabolic drug is 5-fluorouracil.
Claim 7
Dependent Claim
11 words
The method of claim 3, wherein the toxin is a bleach.
Claim 8
Dependent Claim
11 words
The method of claim 4, wherein the bleach comprises a hypochlorite.
Claim 9
Dependent Claim
11 words
The method of claim 4, wherein the bleach comprises a peroxide.
Claim 10
Dependent Claim
34 words
The method of claim 1, wherein step (b) comprises application of a follicle-inactivating compound and ultrasound waves to the skin, the ultrasound waves being sufficient to target the follicle-inactivating compound to the hair follicle.
Claim 11
Dependent Claim
34 words
The method of claim 1, wherein step (b) comprises application of a follicle-inactivating compound and pressure waves to the skin, the pressure waves being sufficient to target the follicle-inactivating compound to the hair follicle.
Claim 12
Dependent Claim
32 words
The method of claim 1, wherein step (b) comprises application of a follicle-inactivating compound and heat to the skin, the heat being sufficient to target the follicle-inactivating compound to the hair follicle.
Claim 13
Independent Claim
35 words
A method of removing a hair from the skin of a mammal, the method comprising (a) mechanically or chemically removing the hair from its follicle, and then (b) treating the follicle with a follicle-inactivating compound.
Claim 14
Independent Claim
35 words
A method of removing a hair from the skin of a mammal, the method comprising (a) mechanically or chemically removing the hair from its follicle, and then (b) treating the follicle with a follicle-inactivating compound.
Claim 15
Dependent Claim
31 words
The method of claim 12, wherein step (b) further comprises application of ultrasound waves to the skin, the ultrasound waves being sufficient to target the follicle-inactivating compound to the hair follicle.
Claim 16
Dependent Claim
31 words
The method of claim 12, wherein step (b) further comprises application of pressure waves to the skin, the pressure waves being sufficient to target the follicle-inactivating compound to the hair follicle.
Claim 17
Dependent Claim
29 words
The method of claim 12, wherein step (b) further comprises application of heat to the skin, the heat being sufficient to target the follicle-inactivating compound to the hair follicle.
