Dihydrotestosterone (DHT)

DHT is an androgen hormone and can be directly associated with facial hair. Along with testosterone, which dihydrotestosterone is synthesized from with the help of 5-alpha reductase, these two androgens are the most important hormones that a beard forms from.

Without DHT, there is no beard. Some bearded men feel that this is incorrect despite scientific evidence and opt to use DHT blockers because “DHT is responsible for hair loss.” What they don't realize is that in spite of using DHT blocking ingredients, such as some essential oils, the reason these men see progress is because DHT is not behind hindered. Remember, topical DHT blockers are nowhere near as potent as oral blockers and pose less risk of some beard hair thinning. But because there's still risk, it is always advised to stay away from potential DHT blockers regardless.

Even if a bearded man feels he is progressing with his facial hair while using a DHT blocker, it could potentially mean he would see better progress without it.

A DHT blocker is something that inhibits the production of dihydrotestosterone by limiting 5-alpha reductase's (5AR) ability to convert testosterone to DHT. Topical DHT blockers that you apply directly to your skin, such as some essential oils, are not as effective as oral solutions like finasteride and dutasteride.

If you want the best beard growth possible, stay away from DHT-inhibiting oils and foods. Men that naturally have high androgen sensitivity likely will not need to worry as much as those that have more of a struggle to grow a beard, but it is still recommended that all men stay away from DHT blockers.
