What to Look For

DHT, or dihydrotestosterone, is a male hormone that is a major contributor to hair loss because it shrinks the hair follicle and creates a waxy substance around the hair roots, which results in male and female pattern hair loss. A DHT-blocking shampoo typically uses zinc, which has been shown to lessen the accumulation of DHT, and vitamin B12 to promote healthy hair growth. Saw palmetto is another common ingredient in DHT-blocking shampoo because, like zinc, it helps slow DHT production.

Common Pitfalls

There are hundreds of DHT-blocking shampoos on the market and they tend to make strong claims about hair regrowth capabilities. However, many of them contain very similar ingredients, so it can be hard to narrow down which shampoo is best for you. Take a look at the ingredient label on the shampoo bottle and look for key DHT-blocking ingredients such as zinc and saw palmetto.

Where to Buy

DHT shampoo can be purchased at many different retailers such as professional salon locations, drugstores, or specialty health retailers. A large third-party hair care site, such as Folica, is a good option to search for DHT shampoo because the site carries many different brands and you can check ingredients and customer reviews before purchasing.


DHT shampoo prices can vary depending on the specific brand. As a rule of thumb, DHT shampoos tend to be more expensive than drugstore shampoos, with prices ranging from $10 to $30. Certain websites offer popular brands of DHT shampoo at discounted prices.

Comparison Shopping

Pay special attention to the ingredient labels when selecting DHT shampoo. Look for the key ingredients to be high up on the ingredient list, which indicates a high concentration.
