It’s also possible for vellus hairs to turn into terminal hairs over time. One example of this is when men start growing thick facial hair, and women don’t. However, it’s also possible for some men to not grow facial hair, or it grows in uneven patches on their face.
There are a number of reasons for this, but the most common reason is that it’s dependent on genetics and ethnicity. In the case of genetics, if the men in your family typically don’t have thick facial hair, then chances are, you might find it hard to grow thick facial hair yourself.
Ethnicity also plays a role when it comes to beard growth. For example, men in Mediterranean countries usually grow thick and longer beards compared to Asian men. Though, this isn’t always the case as some Asian men do grow thick and long beards.
Age can also be a factor, as some men don’t start growing facial hair until they’re close to their 30s. In rare cases, low testosterone levels can also be responsible for a lack of facial hair.
All of these things can play a role in whether or not a person can grow a full beard. Not all men can grow a full beard, and it’s primarily dependent on a person’s genetics and ethnicity.
How Effective is Beard Growth Oil?
Now that we know how facial hair grows, and what factors influence it, we can take a look at whether or not beard growth oil is effective.
The short answer is that for the most part, beard growth oil won’t suddenly make you grow a thick beard, especially if it’s not in your genetics or your ethnicity. Though, there have been some studies conducted on peppermint oil that show some potential for its use in hair growth.
