Treatments for thinning hair are better than ever. There are two fda approved treatments for hair loss - propecia and rogaine. Propecia is a once a day oral pill which blocks the 5-alpha reductase enzyme that creates dihydrotestosterone (dht), the male hormone associated with thinning hair in men with male pattern baldness. Rogaine is a topical lotion available in a regular and extra strength version which stimulates hair growth in both men and women. Other treatments have been shown to be effective although not specifically fda approved for hairloss including avodart and nizoral.
