Does Minoxidil Work For Hair Loss?

18 February, 2021 | Hair Loss

Losing hair and receding hairline can be stressful. The worst part is that the stress of losing your hair everyday further adds to the hair loss, making it a vicious and complicated cycle. Studies in the past have demonstrated that a majority of men and women start experiencing hair loss by the age of 35 that can be attributed to stress, genetics, nutrition, and hormones. This is exactly where Minoxidil comes into the picture.

It interacts with sulfotransferase present on the scalp (when applied topically in the form of a foam or serum) and converts it into minoxidil sulfate that is believed to be Minoxidil's active form. It then shortens the telogen phase (when the hair is resting and the process of hair fall has started) and pushes it into the anagen (growth) phase. Minoxidil extends the growth period of hair and makes the hair grow thicker and longer.

What is Minoxidil?

Minoxidil was originally introduced as an antihypertensive medication and later gained popularity as a topical medicine to promote hair growth. The drug has been used off-label for treating many types of alopecia such as eyebrow hypotrichosis, monilethrix, telogen effluvium, alopecia areata (AA), chemotherapy-induced alopecia (CIA), and scarring alopecia. Minoxidil is primarily effective in treating thinning at the top of the scalp or hereditary hair loss.

Minoxidil is a FDA-approved drug that is used by more than 35 million across the globe for treating androgenetic alopecia or male pattern baldness. It affects two stages of hair - the resting stage (also known as telogen) and the growing phase (anagen). Minoxidil has the unique ability of converting hair in the dormant phase to the anagen phase that means that hair that is not growing for a while gets stimulated to enter the phase of growth. This, in turn, opens up the potassium channel in the roots of our hair and leads to the growth of hair when combined with an improved flow of blood in the body.

Clinically, Minoxidil is used for treating female pattern hair loss and androgenetic alopecia. It is also used off-label for eyebrow enhancement, alopecia areata, beard enhancement, central centrifugal cicatricial alopecia, frontal fibrosing alopecia, loose anagen hair syndrome, Telogen effluvium, Monilethrix, and Chemotherapy-induced alopecia.

Uses

Minoxidil foam and solution are used for stimulating hair growth as part of male pattern baldness treatment. The 2 percent Minoxidil solution and foam are used for helping with hair growth in women who are experiencing hair thinning. Considered to be the mainstay treatment for androgenetic alopecia, Minoxidil is also used as an off-label treatment for a wide range of hair loss conditions.

Mechanism Of Action

A potassium channel opener, Minoxidil has a vasodilation action that expands the blood vessels to promote blood flow in the body. This increased blood flow offers more oxygen and nutrition to the hair follicles that, in turn, enhances new hair growth and prevents hair cell death to treat hair loss (alopecia).

Minoxidil, a piperidino-pyrimidine derivative and potent arteriolar vasodilator, has the ability of opening potassium channels that are located on the smooth muscles of the peripheral artery that leads to hyperpolarization of the cell membrane. Minoxidil enhances cell proliferation and increases cellular DNA synthesis that causes positive effects on hair growth. It also has the ability of stimulating the production of prostaglandin E2 by activating prostaglandin endoperoxide synthase-1 that helps in continuous growth of hair follicles.

Minoxidil is available in formulations of 2% and 5% and Minoxidil 5 for men is commonly used by men across the world to stimulate follicular proliferation and differentiation.

Side Effects

Minoxidil side effects may include fast heartbeat, unusual weight gain, and tiredness. Some of the other Minoxidil side effects may include dizziness, chest pain, and difficulty in breathing especially when lying down.

If you or someone, who has been taking Minoxidil, has serious symptoms (dizziness, flushing, fainting, troubled breathing, or drowsiness) or overdosed, immediate medical intervention should be sought.
