While is no official FDA approved on label dose of oral minoxidil for men or women for the indication of hair loss, clinical studies show us that Low Dose Oral Minoxidil (LDOM) of 1mg taken once daily has a very good effect with very low risk of the side effects for men. For women the dose of 0.25mg, also referred to as Very Low Dose Oral Minoxidil (VLDOM) has been shown to be very effective while greatly reducing the risk of unwanted body hair growth seen more commonly in larger doses.
