A method for inhibiting hair growth in mammals using compositions containing FP receptor antagonists (e.g., prostaglandin F analogs that are block activation of the FP receptor). The compositions can be applied topically to the skin and/or hair. The compositions can arrest hirsutism or hypertrichosis, reverse hirsutism and hypertrichosis, and further prevent hair growth. These compositions can also be used to protect hair from chemical or radiation-induced alopecia or hair loss. These compositions can also be used to inhibit pigmentation of the hair or skin.

This invention provides methods utilizing ketamine for the treatment of motor disorders and/or side effects associated with certain medications used in the treatment of motor disorders. For example, in some embodiments, methods are provided for treating side effects associated with the administration of levodopa to a subject having Parkinson's disease, by administering a dose of ketamine or a pharmaceutically acceptable salt thereof. In particular, the invention provides methods for reducing dyskinesia associated with motor disorder (e.g., Parkinson's disease) treatments, and effective doses of ketamine or a pharmaceutically acceptable salt
