DHT is a byproduct of testosterone metabolism that interferes with the normal growth cycle of hair follicles. High concentrations of DHT make up the hallmark of a chronic condition known as androgenic alopecia.

In a previous article, we listed a number of methods that could potentially lower DHT levels, including medications, light therapy, and dietary choices.

In this article, we will cover the most common topical DHT blockers and their mechanism of action.

Are there better options to topical DHT blocker?

Before you opt for a DHT blocker, it's wise to evaluate the risks:

  • DHT blockers, as the name suggests, block DHT which can cause unwanted side effects.
  • Topical DHT blockers are not always effective, and they are also quite expensive.
  • They're not FDA-approved, and many don't have sufficient testing.

It doesn't really make sense when there's a safe, effective and affordable alternative on the market.

How to choose the best topical DHT blocker?

Now that you understand the importance of a topical DHT blocker, you need to learn how to choose a good brand.

Unfortunately, many companies claim that their product is effective at blocking DHT without any solid scientific evidence.

To summarize, here are the ingredients that you must find in any topical DHT blocker before making a purchase:

Finasteride and minoxidil

These two medications are common in topical DHT blockers. However, make sure you are getting a reputable brand. Some companies would throw the label of having finasteride or minoxidil in their products while they only contain traces.

Saw palmetto

This is an extract from berries of a palm found in southeastern United States. Topical products that contain this ingredient may lower DHT levels, which promotes hair regrowth. In a 2020 review, researchers found some effect of saw palmetto on hair regrowth.

Pumpkin seed oil

Another important ingredient to look for in topical DHT blockers is pumpkin seed oil. Scientists believe that this oil blocks the action of alpha-5 reductase, which is the enzyme that converts testosterone to DHT.


As part of the azole family, this compound is very effective against fungi and also exerts anti-inflammatory actions. In a 2011 study, researchers found that 15 individuals with alopecia experienced hair regrowth after applying ketoconazole to their scalp.

There you have it! Before buying any topical DHT blocker, read the label carefully and make sure it contains at least one of these ingredients.

We hope that this article managed to shed some light on the various types of topical DHT blockers and how they could potentially help with androgenic alopecia.
