A 2% solution of minoxidil in clinical studies, four out of five users claimed Minoxidil helped slow or stop their hair loss. All you need to do is to apply it two times a day with one of the applicators enclosed in the package--it only takes a minute in the morning and a minute at night. Minoxidil is colorless and it's fragrance free so no one will know you're using it. You can even have your hair colored while using Minoxidil. Minoxidil works gradually and works by enlarging the hair follicles, so sometimes Minoxidil helps users regrow their hair by first discarding older, weaker hairs. Minoxidil is clincally proven to help regrow hair and stop hair loss. It is designed for women who have general thinning of the hair on the top of the scalp, and is not intended to treat hair loss in the front of the scalp (receeding hair line). This is a 2% minoxidil solution, which is the maximum recommended for use by women.
