ABSTRACT:
This invention relates generally to an improved medication and treatment serving to darken the color of some hair adjacent to the skin to which the materials of the treatment are applied. The treatment consists of application of topical tretinoin to the skin of a person combined with the application of a lotion containing ammonium lactate to the same skin area. When the treatment is continued on a basis of once or twice per day, the skin of the user assumes a uniform light brown color similar to the countenance of a suntanned appearance within a period of a few weeks, and some hair adjacent to the skin to which the materials of the treatment are applied is darkened.
