Minoxidil is a medication that is commonly used for the treatment of high blood pressure, and for the treatment of cosmetic conditions such as baldness. Minoxidil is a vasodilator that speeds up blood flow from the heart to the scalp. The idea behind this is that since the scalp has a high concentration of hair follicles, more oxygen and nutrients will be delivered to these follicles and thus cause hair regrowth. There are two different types of Minoxidil products available by Minoxidil Hair Regrowth Treatment: a 25% solution, and a 5% solution. The 5% solution is not recommended for people that have sensitive skin, as it can lead to skin irritation and redness. Minoxidil is FDA approved, and has been shown to slow hair loss in women with female-pattern hair loss. Minoxidil is an FDA approved medication that treats high blood pressure, and is also used for cosmetic purposes such as baldness.
