Composition for treating hair against chemical and photo damage

A cosmetic composition for treating hair comprising:

• a. from about 0.1 to 50% by weight of a hydrolyzed protein comprising anionic and cationic amino acids, wherein the molar ratio of the anionic amino acids to cationic amino acids of the hydrolyzed protein is at least 2.1:1.0, wherein the hydrolyzed protein comprises at least 0.25% by weight of a sulphur-containing amino acid, and wherein the hydrolyzed protein has an average molecular weight of less than 500,000 daltons;
• b. a polyamino cationic agent, wherein the cationic polyamino agent is a peptide, wherein at least 2 of the amino acids of the peptide are cationic amino acid compounds selected from the group consisting of histidine, arginine, lysine, hydroxylysine, ornithine or combinations thereof;
• wherein the ratio of the amino groups of the peptide to the anionic amino acids of the hydrolyzed protein is from about 0.2:1 to 2:1;
• and
• c. from about 1 to 99.9% by weight of cosmetic carrier.

• b. a polyamino cationic agent having the formula:
• ##STR3## where n=1-6 and R.sub.1, R.sub.2, R.sub.3, R.sub.4, and R.sub.5 are selected from the group consisting of H, an alkyl group or compound comprising one or more amino groups, wherein the molar ratio of the amino groups of the polyamino cationic agent to the anionic amino acids of the hydrolyzed protein is from about 0.2:1 to 2:1;
• c. from about 1 to 99.9% by weight of cosmetic carrier.
