Oral Minoxidil is a medication that is FDA-approved to treat high blood pressure, but it is also sometimes prescribed off-label in lower dosages for hair loss treatment. When clinical trials were being conducted with oral Minoxidil for blood pressure, many patients reported longer, thicker, and darker hairs growing on the body, including the hair on their scalp. For this reason, some doctors prescribe this medication off-label as an alternative to hair loss medications like Finasteride that modulate DHT in the body, or as an add-on to other topical or oral hair loss treatments.
