What Triggers Hair Growth?
Did you know that aside from your lips, the palms of your hands and the soles of your feet, most of your body is covered in hair?
Some places, such as the arms, legs, and some parts of the face, contain thin and short hairs called vellus hairs. In contrast, the hair on our head, eyebrows, facial hair, and pubic hair is longer and thicker, and is called terminal hairs.
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 is 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.
