Abstract

Formulations, kits, and methods for rebuilding the disulfide bonds in keratin found in hair, skin, or nails. Hair that is damaged due to a hair coloring treatment and/or other reducing treatment, such as during a permanent wave, can be treated with the formulations containing one or more active agents. The formulations may be applied subsequent to a hair coloring treatment or simultaneously with a hair coloring treatment. Use of the active agent formulations during a permanent wave treatment prevents the reversion of the hair to its previous state, for at least one week, preferably at least three months, more preferably at least one year, most preferably greater than one year, after one or more than one application of the formulation. Application of the active agent formulation to skin or nails can help repair damaged disulfide bonds due to natural wear and tear or natural aging.

Claims

1. A method for bleaching hair comprising:

(a) applying to the hair a first formulation comprising a bleaching agent; and

(b) applying to the hair a second formulation comprising an active agent, wherein the second formulation does not contain a coloring agent,

wherein the active agent has the formula;

2. The method of claim 1, wherein the linker Z is an alkyl group, alkenyl group, cycloalkyl group, cycloalkenyl group, aryl group, heterocycloalkyl group, or heteroaryl group,

3. The method of claim 1, wherein the linker Z is a C_1-4 alkyl group.

4. The method of claim 3, wherein the alkyl group is substituted with one or more substituents replacing a hydrogen on one or more carbons of the alkyl hydrocarbon backbone or the alkyl group is substituted with one or more heteroatoms within the hydrocarbon carbon backbone, or a combination thereof, and

wherein the substituents are selected from the group consisting of oxo, hydroxyl, carboxyl, amido, and amino groups.

5. The method of claim 1, wherein the active agent is present in an amount ranging from about 0.01 wt % to about 10 wt % of the second formulation.

6. The method of claim 1, wherein the active agent is present in an amount ranging from about 0.5 to 3 wt % of the second formulation.

7. The method of claim 1, wherein the second formulation is in the form of a gel, cream or lotion.

8. The method of claim 1, wherein step (b) is repeated one or more times.

9. The method of claim 1, further comprising:

(c) rinsing, shampooing, or conditioning the hair, or a combination thereof, wherein step (c) occurs subsequent to step (b).

10. The method of claim 1, wherein the active agent is selected from the group consisting of:

11. The method of claim 1, wherein the first formulation and the second formulation are mixed at the time of use and prior to application.

12. A method for bleaching hair comprising:

(a) applying to the hair a first formulation comprising a bleaching agent; and

(b) applying to the hair a second formulation comprising an active agent, wherein the second formulation does not contain a coloring agent, wherein the first and second formulations are in separate containers or compartments,

wherein the active agent has the formula;

13. The method of claim 12, wherein the linker Z is an alkyl group, alkenyl group, cycloalkyl group, cycloalkenyl group, aryl group, heterocycloalkyl group, or heteroaryl group,
