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) mixing a bleach powder and a developer to form a bleaching formulation;

(b) mixing an active agent formulation comprising an active agent with the bleaching formulation to form a mixture, wherein the active agent is maleic acid; and

(c) applying the mixture to the hair;

wherein the active agent in the mixture is at a concentration ranging from about 0.1% by weight to about 50% by weight.

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

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

4. The method of claim 1, wherein the active agent is present in an amount ranging from about 1 wt % to about 15 wt % of the active agent formulation.

5. The method of claim 1, wherein the active agent is present in an amount ranging from about 0.1 wt % to about 5 wt % of the mixture.

6. The method of claim 1, wherein the active agent is present in an amount ranging from about 0.1 wt % to about 3 wt % of the mixture.

7. The method of claim 1, wherein the active agent formulation further comprises one or more excipients in an amount ranging from about 50 wt % to about 90 wt % of the active agent formulation.

8. The method of claim 1, wherein the active agent formulation is in the form of a liquid.

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

10. The method of claim 1, further comprising:

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

11. The method of claim 1, wherein step (b) occurs at the time of use and prior to application of the mixture to the hair.

12. The method of claim 1, further comprising:

(d) applying a second active agent formulation comprising maleic acid,

wherein step (d) occurs subsequent to step (c).

13. The method of claim 12, wherein the second active agent formulation further comprises a conditioning agent.

14. The method of claim 13, wherein following step (d) breakage of the hair is decreased by at least 5% compared to hair bleached with the bleaching formulation in the absence of the active agent.

15. The method of claim 13, wherein following step (d) breakage of the hair is decreased by at least 10% compared to hair bleached with the bleaching formulation in the absence of the active agent.

16. The method of claim 13, wherein following step (d) breakage of the hair is decreased by at least 20% compared to hair bleached with the bleaching formulation in the absence of the active agent.

17. The method of claim 13, wherein following step (d) breakage of the hair is decreased by at least about 40% compared to hair bleached with the bleaching formulation in the absence of the active agent.

18. The method of claim 13, wherein following step (d) breakage of the hair is decreased by at least 50% compared to hair bleached with the bleaching formulation in the absence of the active agent.

19. The method of claim 13, wherein the conditioning agent in the second active agent formulation is present in an amount ranging from about 0.1 to about 5% by weight of the second active agent formulation.

20. The method of claim 19, wherein the conditioning agent in the second active agent formulation comprises behentrimonium methosulfate and stearamidopropyl dimethylamine.

21. The method of claim 19, wherein the second active agent formulation is in the form of a cream.

22. The method of claim 21, wherein the second active agent formulation comprises water, glycerin, propylene glycol, cetearyl alcohol, phenoxyethanol, behentrimonium methosulfate, quaternium-91, and stearamidopropyl dimethylamine.

23. The method of claim 12, wherein the maleic acid is present in an amount from about 1 wt % to about 10 wt % of the second active agent formulation.

24. The method of claim 1, wherein following step (c) breakage of the hair is decreased by at least 5% compared to hair bleached with the bleaching formulation in the absence of the active agent.

25. The method of claim 1, wherein following step (c) breakage of the hair is decreased by at least 10% compared to hair bleached with the bleaching formulation in the absence of the active agent.

26. The method of claim 1, wherein following step (c) breakage of the hair is decreased by at least 20% compared to hair bleached with the bleaching formulation in the absence of the active agent.

27. The method of claim 1, wherein following step (c) breakage of the hair is decreased by at least 40% compared to hair bleached with the bleaching formulation in the absence of the active agent.

28. The method of claim 1, wherein following step (c) breakage of the hair is decreased by at least 50% compared to hair bleached with the bleaching formulation in the absence of the active agent.

29. The method of claim 1, wherein following step (c), the hair is lighter compared to the hair prior to step (c).

30. The method of claim 1, wherein the mixture does not comprise a dye precursor.
