Minoxidil For Hair: Benefits And How It Works

Anyone who has faced hair loss or is struggling with hair growth has probably heard of Minoxidil. If you are curious to know if Minoxidil works for hair, you have come to the right place. It is one of the most recommended treatments to stimulate hair growth. Explore the working and benefits of Minoxidil and why doctors recommend it. Continue reading.

What Is Minoxidil?

Minoxidil, which commonly goes by the trade name Rogaine, was developed by Upjohn Company in the late 1950s to treat ulcers. But today, the medication is used as an oral vasodilator to treat blood pressure (1). This over-the-counter medication is also used to treat male pattern baldness. However, it is believed to work best on those less than 40 years of age.

Minoxidil is available as a tablet, ointment, or foam. It can be taken orally or applied topically to the affected area. Let us look at the research concerning minoxidil.

What Does Research Say About Minoxidil And Hair Regrowth?

Minoxidil was found to be quite effective when used to reverse hair loss from medication. In the study, using minoxidil regularly had decreased the duration of hair loss due to chemotherapy (2).

In another study, the participants (men) were categorized into three groups. While the first two groups were given 5% minoxidil and 2% minoxidil, the third was given a placebo. The study found that men who used 5% topical minoxidil showed more effective hair growth than those in the other two groups (3).

Topical minoxidil used along with finasteride was found to be more effective in treating hair loss than using either of the medication alone (4). However, finasteride is not recommended for pregnant women due to its potential teratogenic effects on the fetus (physical malformations) (5).

In another study, using 5% topical minoxidil and low-level light therapy (a red light device used on the scalp) showed an increased improvement from androgenic alopecia (6).

Much of the research does state that minoxidil may help with hair regrowth. But how does it work?

How Does Minoxidil Work For Hair?

Minoxidil is a vasodilator and is used to treat blood pressure. It helps expand the blood vessels, leading to an increase in blood flow in the body. It is believed that this property of minoxidil may help increase the blood flow to the hair follicles, encouraging hair growth (7). However, more information on the mechanism of minoxidil in hair growth is warranted.
