Who doesn't love to spice up their regular look with stylish beards and moustaches? From a neatly trimmed goatee to a trendy stubble, every man enjoys trying out a new beard style. However, for some, growing a beard turns out to be a slow and nearly impossible task.
Several factors can affect your beard growth. In this article, we explain to you a few reasons behind the difficulty of growing out your beard and ways to maximize the growth.
Is Everyone Able To Grow A Beard?
Some men may find it difficult to grow a beard. For some, the growth rate of facial hair is pretty slow and it seems impossible to have a full-covered beard. Unfortunately, there is no such proven remedy to induce the growth of facial hair.
Men with unfavorable genetic characteristics may not be able to grow a thick beard and get their desired beard style.
There are several myths regarding the growth of a beard. Many people mistakenly believe that shaving makes facial hair grow thicker. However, there is no proof behind this theory. Shaving can't increase the number of hair follicles beneath your skin and cannot even raise the hair growth rate.
Signs You Can't Grow A Beard
There are multiple factors influencing the growth and look of your beard. Here are the key factors indicating your ability or disability to grow a beard.
Genetics is one of the major determining factors behind the thickness of your beard growth. If your father and grandparents have a thin beard or uneven growth of facial hair or no hair at all, you’ll probably bear the same trend.
In earlier days, there was a common belief that your potentiality (or lack thereof) to grow a beard is controlled by your mother's genes. But, that was an entirely wrong concept. A 2014 study showed that a person’s genetic makeup is a random mix of both parents’ DNAs.
Did You Know?
Androgen hormones influence different masculine traits in men. The 5-alpha reductase enzyme of your body converts the androgen hormone testosterone into dihydrotestosterone (DHT). This DHT stimulates the growth of facial hair.
Besides genetics, age too is a highly influential factor in determining your beard’s growth. Usually, men begin experiencing facial hair coverage during puberty.
Depending on genes, that age varies from 13 to 19.
Some people can even take a few more years to grow a beard. It can even delay up to the early 20s to get the increased facial hair coverage. And in most cases, one can have a full beard growth by the 30s. So, you must wait until your 30s to confirm that you can't grow a beard.
Your originality can affect the growth pattern of your facial hair . A study on The male beard hair and facial skin – challenges for shaving reveal that Chinese, Mexican, and Native American men tend to have less facial hair than Caucasian men .
It also states that on average, the diameter of human hair varies from 17 to 180 micrometers. The thickness of individual facial hair contributes to a fuller-looking beard.
4. Alopecia Areata
Alopecia Areata , an autoimmune disease, can cause extensive hair loss. In this condition, your immunity system attacks the hair follicles on your scalp and face, which causes hair to fall out in patches.
5. Unhealthy Habits
Even after having bearded ancestors, you may experience a delay or irregularity in your beard growth. Along with favorable genes and age, you need to follow healthy lifestyle habits to influence your beard growth.
A balanced diet, regular exercise, and deep sleep are essential. These three healthy habits can fuel your body with enough nutrients and energy that contribute to non-stop hair growth.
6. Low Testosterone Levels
Testosterone is a hormone that largely affects facial hair growth. Low level of this hormone means less chances of growing a beard.
A healthy eating habit nourishes your body with the required vitamins and minerals. Also, regular exercise can help to enhance the level of testosterone, which can also influence hair growth.
How To Know If You Can Grow A Beard?
1. Bearded Ancestors
Your genes contribute to growing a lush and full beard. Genes from both parents can influence your hair growth, depending on the dominant genes on your chromosome. Usually, paternal genes dominate the facial hair growth pattern.
But if your paternal ancestors belong to the population that tends to grow less facial hair than usual, your maternal genes are your only hope.
2. A Hairy Body
If you have body hair everywhere (shoulders, chest, arms, and legs), you are most likely to grow facial hair too.
Also, if you hit puberty early on, then you have a high chance of having a well-covered and dense beard. On the contrary, if you tend to grow less hair during your teenage years, you may have a no- or patchy-beard future.
3. A Healthy Lifestyle
Apart from genes, a healthy lifestyle is crucial to influencing your bear growth. Eat a healthy diet enriched with fruits, veggies and seafood (especially those rich in Omega-3 fatty acids and biotin).
Next comes physical activity. An active lifestyle with regular exercise and outdoor sports can keep your hormone levels well-balanced and improve your testosterone levels. Testosterone can influence your hair follicles and enhance the growth of your facial hair.
4. Good Stress Management Capacity
Stress can also influence your beard growth. A study in 2017 showed that people who experience stress regularly are prone to hair loss, especially when their hair goes through the growing phase.
How To Grow A Beard?
If you want to grow a stylish beard, there is no shortcut. Your genes only decide whether you can have it or not. But it is entirely up to you how you want to groom it.
Growing your beard for the first time requires patience, dedication, and guidance. Minor changes to your lifestyle can help you to grow a thick beard. Here are some instances of lifestyle changes that can maximize your genetic potential to grow facial hair:
1. Eat Healthy
A healthy and balanced diet enriched with Omega-3 fatty acids  and biotin helps you to avoid nutrient deficiencies and influence healthy beard growth.
You may not have a full-grown beard as a teenager or in your early 20s. For some people, beard growth reaches its extremity by the 30s. So, you must wait to grow your beard thicker.
3. Reduce Stress
There are studies supporting the fact that stress can induce scalp hair loss. So, there is a chance that stress may also affect your facial hair quality. However, there is no such evidence to prove it.
But stress can also disturb your sleeping pattern and sleep quality. A good sleeping routine is essential to regulate your hormones well and maintain their levels in your body – which support your skin and follicles to work at 100%.
4. Avoid Smoking
Studies showed that smoking could affect your hair health and growth. So you should completely give up on or at least reduce your cigarette consumption.
Your genes play a key role in the growth of your facial hair. If your genetic factors are not aligned, no external support or hormonal supplement can help you grow your beard. In such cases, beard implantation can be an option. This is an expensive and surgical procedure comprising some risks as well.
What Age Does Full Beard Come In?
On average, a man can have a full beard growth at around 18 years. But for some people, the time can vary up to 30 years to get their complete beard growth. So, you have to be patient till your 30s to experience the complete growth of your facial hair.
Does No Beard Mean Low Testosterone?
That's not entirely true. Testosterone can influence facial hair quality, but when your genes are not favorable for beard production, testosterone can’t help. Most men have similar levels of testosterone, including men without a beard.
Not every man can grow a beard. External support may help you grow a beard in certain cases. But if your genes are not aligned, or you have a disease like Alopecia, you won’t be able to grow a beard.
