## Abstract

Provided is a method for treating hair damage by contacting the hair with an effective amount of an epoxysilicone. The method may be used for treating hair damage caused by a hair altering process that is capable of damaging hair, for example, hair lightening/bleaching procedures, hair relaxing procedures, hair dyeing procedures, hair permanent waving, and hair smooting. Also provided is a composition and a product, which include a hair damage treating effective amount of the epoxysilicone.

## Claims

### Claim 1

A method for treating hair damage, the method comprising contacting the hair with an effective amount of a compound of formula (Ic):

### Claim 2 (depends on 1)

The method of claim 1, wherein the hair damage is caused by chemical damage, sunlight, air oxidation, mechanical stress, or a combination thereof.

### Claim 3 (depends on 2)

The method of claim 2, wherein the hair damage is caused by a hair altering process that is capable of damaging hair fibers.

### Claim 4 (depends on 3)

The method of claim 3, wherein the hair altering process comprises applying an oxidative hair lightening agent to the hair.

### Claim 5 (depends on 4)

The method of claim 4, wherein the compound of formula (Ic) and the oxidative hair lightening agent are combined before application to the hair.

### Claim 6 (depends on 5)

The method of claim 5, wherein the concentration of the compound of formula (Ic) is from about 0.1 wt % to about 10 wt % after being combined with the oxidative hair lightening agent.

### Claim 7 (depends on 4)

The method of claim 4, wherein the oxidative hair lightening agent is prepared by combining at least one persulfate and at least one peroxide.

### Claim 8 (depends on 7)

The method of claim 7, wherein the persulfate comprises potassium persulfate, ammonium persulfate, or a combination thereof.

### Claim 9 (depends on 7)

The method of claim 7, wherein the peroxide comprises hydrogen peroxide.

### Claim 10 (depends on 3)

The method of claim 3, wherein the hair altering process comprises applying a hair relaxing agent to the hair.

### Claim 11 (depends on 10)

The method of claim 10, wherein the compound of formula (Ic) and the hair relaxing agent are combined before application to the hair.

### Claim 12 (depends on 11)

The method of claim 11, wherein the concentration of the compound of formula (Ic) is from about 0.1 wt % to about 10 wt % after being combined with the hair relaxing agent.

### Claim 13 (depends on 10)

The method of claim 10, wherein the hair relaxing agent is prepared by combining at least one metal hydroxide and at least one alkaline salt of guanidine.

### Claim 14 (depends on 13)

The method of claim 13, wherein the metal hydroxide comprises calcium hydroxide.

### Claim 15 (depends on 13)

The method of claim 13, wherein the alkaline salt of guanidine comprises guanidine carbonate.

### Claim 16 (depends on 3)

The method of claim 3, wherein the hair altering process comprises applying to the hair an oxidative hair dyeing agent.

### Claim 17 (depends on 16)

The method of claim 16, wherein the compound of formula (Ic) and the oxidative hair dyeing agent are combined before application to the hair.

### Claim 18 (depends on 17)

The method of claim 17, wherein the concentration of the compound of formula (Ic) is from about 0.1 wt % to about 10 wt % after being combined with the oxidative hair dyeing agent.

### Claim 19 (depends on 16)

The method of claim 16, wherein the oxidative hair dyeing agent is prepared by combining at least one permanent hair dyeing agent with at least one peroxide.

### Claim 20 (depends on 19)

The method of claim 19, wherein the permanent hair dyeing agent comprises two or more permanent hair dyes.

### Claim 21 (depends on 19)

The method of claim 19, wherein the peroxide comprises hydrogen peroxide.

### Claim 22 (depends on 1)

The method of claim 1, wherein the compound of formula (Ic) is in the form of an aqueous emulsion.

### Claim 23 (depends on 1)
