## Abstract

Compositions, formulations, kits and methods for temporarily or semi-permanently transforming the shape of individual hair filaments or keratinous fibers (curling, waving or straightening) by applying no heat or heat below about 300° F. to prevent damage to the keratinous fibers.

## Claims

### Claim 1

A method for treating a keratinous fiber of a mammal, the method comprising:
applying a keratinous fiber styling composition to the keratinous fiber; wherein the styling composition comprises:
a cosmetically suitable carrier;
a polymerizable monomer selected from a member of the group consisting of soy protein and hydrolyzed silk (silk peptide); and
at least one protein fixing agent selected from a member of the group consisting of 2-propanone, ethyl lactate, butyl lactate, butanone, t-butanol and n-butanol; and
activating the protein fixing agent to initiate an in-situ polymerization reaction on the keratinous fiber by applying heat to the keratinous fiber at a temperature below 300° F.

### Claim 2 (depends on 1)

The method of claim 1, wherein the protein fixing agent is activated by a member selected from the group consisting of: warm water, flat iron, blow dryer, heated brush, heated brush with a rotating drum and curling iron.

### Claim 3 (depends on 1)

The method of claim 1, wherein the heat is applied to the keratinous fiber for about 1 to 10 seconds.

### Claim 4 (depends on 1)

The method of claim 1 wherein the heat is applied to the keratinous fiber at a temperature between 212° F. to below 300° F.

### Claim 5 (depends on 1)

The method of claim 1, further comprising a step of washing and rinsing the keratinous fiber prior to applying the styling composition.

### Claim 6 (depends on 1)

The method of claim 1, further comprising a step of rinsing the keratinous fiber after about 2-5 minutes.

### Claim 7 (depends on 1)

The method claim 1, further comprising a step of blow drying the keratinous fiber prior to applying heat.

### Claim 8 (depends on 1)

The method of claim 1, wherein the styling composition further comprises a quaternary ammonium salt.

### Claim 9 (depends on 8)

The method of claim 8, wherein the quaternary ammonium salt is quaternium-80.

### Claim 10 (depends on 1)

The method of claim 1, wherein the level of protein fixing agent in the styling composition is from about 1 wt % to about 25 wt % of the total composition.

### Claim 11 (depends on 1)

The method of claim 1, wherein the level of protein fixing agent in the styling composition is from about 1 wt % to about 10 wt % of the total composition.

### Claim 12 (depends on 1)

The method of claim 1, wherein the level of protein fixing agent in the styling composition is from about 1 wt % to about 5 wt % of the total composition.
