Genetics, Hormones and How They Effect Your Beard Growth!

Genetics, Hormones and How They Effect Your Beard Growth!

Have you ever wondered why some people have full, thick beards but are bald or have hair loss? It’s because beard and hair growth are affected by the presence of two similar hormones: Testosterone and Dihydrotestosterone (DHT).
It is well known that genetics plays a huge role in beard growth. But how exactly does genetics play a role in beard growth?
Firstly, keep in mind you inherit genes from both parents. So, while the role of DNA is not fully understood yet, research has shown that a marker in the LNXI gene on chromosome 4 plays a role in facial hair growth. Specifically, variations in this gene seem to influence how thick or sparse your facial hair grows. There is still a lot of debate about ethnic phenotypes within the science community. While persons of the same ethnicity can usually have commonalities in thickness patterns, the growth pattern can vary greatly.
Secondly, androgen hormones. These hormones include the two mentioned above, testosterone and DHT. These two androgen hormones are the main primary sex hormones that control beard growth. 


The hormone Testosterone is found in humans and other animals that is primarily produced in the testicles and ovaries. Testosterone levels can vary from person to person. Standard testosterone range produced by the testes in adults, is between 280 and 1,100 nanograms per deciliter (ng/dL). Standard testosterone range produced by the ovaries in adults, is between 15 and 70 ng/dL.

We have two types of hair on our body, terminal (hair that we are born able to see, i.e., eyebrows, scalp hair) and vellus (sometimes known as “peach fuzz”) hair. When Testosterone and DHT bind to the androgen receptors on your hair follicles, they promote vellus hairs to be replaced by coarser, darker terminal hair, such as your facial hairThe sensitivity of your androgen receptors on your hair follicles can also plays a vital role in beard growth. 

DHT is a by-product of testosterone. It contributes to increased body hair due to it being more potent than testosterone, muscle mass and changes in how adipose (fat) tissue is stored around your body. About 5-10% of testosterone in all people is transformed to DHT with the help of an enzyme called 5-alpha reductase. That leaves a whole lot of testosterone to do what it does best – help you build muscle, improve your mood, give you stronger bones and a help you have great sex.

But what does DHT actually do? DHT works differently on your scalp and facial hair. It suffocates your scalp hair follicles so they can’t product hair (that’s not what we want!), but there is some evidence to suggest that DHT influences linear beard growth, which means how fast your beard grows. 

Now we know how genetics and hormones influence beard growth.

Choose The Right Products for your Beard 

    Choosing the right products for hair growth can be overwhelming, so we’ve simplified it for you. We've developed a range of uniquely crafted Beard OilsBeard Balms and Solid Shampoo Bars contain the right oils, vitamins and nutrients need to provide the hair follicles an optimal environment for growth and balance. The result is all-day softness, incredibly lightweight and long-lasting beard care and growth promoting products.

    Incorporate Testosterone Boosting Foods into your Diet

    When it comes to testosterone, there are certain foods that can boost your testosterone levels, potentially having a positive growth impact on your facial hair. 


    It's well known that the rate at which your facial hair will grow in, as well as its fullness, is largely determined by genetics. Specially, testosterone and it's by-product, DHT. Since beard growth is largely determined by genetics, it doesn't mean you don't need to maintain good facial hair and skin hygiene. Hair can grow at different rates and variations for everyone, so you don't know when your beard may grow in. Read through our other educational blogs about hair growth, beard oil benefits, and keeping yourself healthy through diet and exercise to help boost your overall testosterone.
