Abstract
The present invention describes a method for targeted and specific delivery of beneficial compounds, including dyes, proteins, and nucleic acids for gene therapy, to hair follicle cells using liposomes encapsulating the beneficial compound. Particularly preferred methods describe delivery of tyrosinase to the hair follicle for the purpose of improving hair color or condition, either by encapsulating the compound in liposomes, or by encapsulating a nucleic acid capable of expressing the protein in liposomes.
