Almost two-thirds of men face hair loss and male pattern baldness before 35. One of the major causes of pattern hair loss is the hormone dihydrotestosterone(DHT), which shrinks hair follicles.

To prevent hair loss, you may have come across DHT blocker shampoos, but does DHT blocking shampoo work for hair loss? This article will explore the ingredients in anti-DHT shampoo, how they work, their potential side effects, and safety concerns.

What Is DHT?

“DHT, also known as dihydrotestosterone, is an androgen responsible for growing body hair, developing deep voice, and increasing muscle mass in men.”

While this hormone helps beard growth and other body hairs, it is a major cause of pattern baldness (androgenetic alopecia) in males. Male pattern hair loss treatments utilize anti-DHT products to limit its effects, stop hair fall, and enhance hair growth. It may also induce hair loss in females.

How Does DHT Cause Hair Loss?

When the 5-alpha reductase enzyme converts testosterone, it forms DHT. This hormone has a high capability of binding with androgen receptors in hair follicles which shrinks them causing hair loss.

  • DHT contributes to hair thinning in women.
  • The hair growth cycle is slowed down.
  • Patchy hair loss occurs in men.

DHT-blocker shampoos are made to prevent hair loss and improve hair health. Dihydrotestosterone is essential for male characteristics development but its side effects are undesirable.

  • Shampoos with anti DHT ingredients block the hormone by reducing its conversions from testosterone.
  • Less DHT binding to androgen receptors reduces hair loss in males.

How To Use A DHT-Blocker Shampoo?

To maximize the effectiveness of DHT-blocker shampoos, follow these tips:

  • Check the active anti-DHT ingredient in your shampoo.
  • Apply the shampoo and leave it for 10 minutes before washing.
