Abstract
Abstract Disclosed is a composition for regulating hair growth comprising a safe and effective amount of a polypeptide having the structure of those derived from dermal papilla cells with characteristics of apparent isoelectric pH/molecular weight selected from the group consisting of pI 5.1/45kD, pI 5.2/43kD, pI 5.2/40kD, pI 7.3/25kD, pI 7.4/25kD, or active fragment of these polypeptides, and mixtures thereof; and a pharmaceutically-acceptable carrier.
