Nevertheless, guys who can’t grow beards can take solace in the fact that, men who are more sensitive to testosterone, are also more likely to lose their head of hair and go bald. It’s no wonder bald men with beards are trending.

Age

If your genetics isn’t the problem, then age is another factor that can cause you to wonder if all men can grow beards. Given that most guys end puberty and stop growing around the age of 21, many men are under the disillusion that facial hair growth should reach its prime at that same age. Instead, your beard’s growth rate will peak at around 30 years of age; although some researchers believe it keeps on increasing the longer you live.

If you’re younger than 25 years old and have only grown a bit of stubble in a couple weeks, don’t give up. Will you ever grow a beard? Maybe. Just be patient and don’t shave yet – let nature take its course.

Lack of Testosterone

Another important factor is the amount of testosterone in your body. Testosterone is the male sex hormone, and a lack thereof is undeniably one of the most common causes of poor beard growth. A lack of testosterone in your body (as a result of a poor diet, a lack of exercise, or stunted hormone function) can greatly reduce your chances of growing a beard.

Changing your lifestyle can increase and maximize testosterone levels in your body. For example, studies demonstrate that weightlifting can boost testosterone, while a proper diet and sufficient rest can help ensure your facial hair grows at its fastest rate.

Other Factors Affecting Beard Growth

Although those three variables are the most vital ones when it comes to facial hair growth, there are other reasons why you may not be able to grow a beard. In brief, these are:

• Lack of sleep, which may stunt testosterone production
• Skin conditions, such as alopecia (when your immune system attacks hair follicles)
• Drug consumption
• Damaged skin
