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 answers the question "how to remove DHT from scalp". This includes medications, light therapy, and dietary choices.

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

What is DHT?

DHT (dihydrotestosterone) is a crucial male hormone naturally present in men’s bodies, significantly influencing their sexual development, especially during puberty.

For instance, DHT is responsible for the growth of the prostate, facial hair, and body hair. Although men have higher levels of DHT, it is also present in women.

Excessive levels of DHT can lead to issues like excessive body hair and scalp hair loss in women, which is why DHT blockers can be helpful.

What are DHT blockers?

DHT blockers are treatments, including medicines, shampoos, and natural foods, designed to prevent DHT from attacking and shrinking hair follicles.

These blockers work by either inhibiting the enzyme 5-alpha reductase, which converts testosterone to DHT, or by stopping DHT from binding to androgen receptors. This way, they reduce DHT's impact without causing hormone imbalances from reduced testosterone levels.

Imagine your hair follicles as little plants in a garden. DHT is like an aggressive weed that chokes them out.

Using DHT blockers is like laying down a protective barrier to keep those weeds at bay, allowing your hair to grow strong and healthy.

    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

    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.

    Ketoconazole

    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.

    The best topical DHT blockers on the market

    There are many topical DHT blockers on the market. However, not all of them are created equal. With so many options, it can be difficult to find the best topical DHT blockers that work for your needs.

    Here are the best topical DHT blockers and which ones are worth your time and money.
