The present invention describes a hypoallergenic cleansing, cosmetic, conditioning or dermatological composition for treating skin or hair that contains serum albumin in an amount effective to achieve cleansing, conditioning, wound debrisment or other cosmetic benefit. The compositions may be delivered to hair or skin via soap, shampoo, cream, oil, lotion, gel, gel-based ointment and the like.

The serum albumin compositions are preferably prepared using human serum albumin produced by recombinant means, and such compositions are useful in that they allow the albumin to be absorbed in the surface of skin or hair so as to replenish the structure of these tissues when utilized. The disclosed compositions can be used safely and effectively with reduced likelihood of allergic reactions.
