For anyone staring a little too long at their hairline in the mirror, minoxidil might seem like a miracle in a bottle. This popular hair regrowth treatment that has been making rounds on TikTok has given hope to millions dealing with thinning hair, but is it really the magic fix it’s made out to be?
While some swear by the newfound volume and baby hairs sprouting along their scalp, others find themselves dealing with unexpected side effects. So, is minoxidil a game-changer or just another gamble in the quest for fuller hair? Let’s weigh the pros and cons before you lather up.
Minoxidil, as defined by Medical News Today, was originally designed for high blood pressure, and was later developed for hair loss treatment in 1987. It is said to be available in 2% or 5% concentrations and is marketed under the brand names Rogaine and Theroxidil. It also mentioned that the Food and Drug Administration has approved minoxidil and finasteride as treatments for male hair loss.
The above source continues to explain how this hair treatment works, it is applied to the head in either a solution or foam, with foam allowing easier penetration and increased delivery. “A scalp enzyme called sulfotransferase converts the minoxidil into a salt called minoxidil sulfate. It works by shortening the telogen, or resting, phase of the hair and causes the hair to enter the anagen or growing stage. There is some evidence that minoxidil can increase the thickness of the hair.”
Pros
Rogaine, an FDA-approved topical hair growth medication, is said to be easy to use and effective in treating hair loss, according to Hairdoc. Rogaine is said to be effective, with 84.3% of men deeming it effective in regrowing hair.
The publication also mentions that topical Rogaine, which includes anti-DHT additives, provides greater results and reduces the chance of side effects. “While Rogaine also comes in a medication that can be taken orally, the topical version provides better results while reducing the chance of side effects.”
Cons
The GoodXR publication claims that minoxidil can cause side effects such as scalp irritation, unwanted hair growth, hair texture changes, and rare systemic side effects such as heart palpitations. Scalp irritation while using this product is said to be common due to the ingredient propylene glycol in the liquid formulation, which can cause skin reactions. If you experience this, it is advised that you use the foam formulation or a different form of minoxidil.
Unwanted hair growth is more common in women, but it is usually reversible, claims the above source. “As mentioned above, oral minoxidil is used to treat high blood pressure at normal dosages. It circulates in your bloodstream and affects some of your organs, including your heart.”
