    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:


    This medication is common in topical DHT blockers. However, make sure you are getting a reputable brand. Some companies would throw the label of having finasteride in their products while they only contain traces. There are also many alternative to finasteride. Read more in our journal!

    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.
