What damages beard growth?

If you've ever wondered why your beard isn't growing as fast as you'd like, it's important to understand what can affect its growth. There are many factors that may be affecting your beard growth and making it slower than you'd like. They include:

Shaving against the grain

Shaving against the grain can cause razor burn and ingrown hairs, which can lead to red bumps.

To avoid these issues, use a sharp razor and shave with the direction of beard growth—go with your hair instead of against it. This will help reduce breakage from repetitive strokes against your skin, making it less likely that you'll have stubble or irritation afterward.

Can a Poor diet damage beard?

Nutrient deficiencies are a common cause of poor beard growth. Some of the most likely culprits include:

  • Low protein—sometimes caused by eating too few calories

  • Low vitamin D—because your body can't make it on its own and you don't get enough exposure to sunlight

  • Low iron—you need it to produce red blood cells, which carry oxygen throughout the body and support good hair growth

  • Zinc deficiency (and elevated copper levels) can be caused by certain medications, such as antibiotics or birth control pills

Your genetics

Your genes can play a role in how quickly or slowly your beard grows. Some men can grow thick, bushy beards in just a few weeks while others have to wait months before they see any results. In some cases, genetics may also impact the appearance of your facial hair.

Fast growth can lead to dandruff and split ends that are more prone to breakage than you'd expect on normal hair—but slow growth means you're going without an awesome beard for longer than any man should ever go without one!

Skin diseases

Skin diseases such as psoriasis, acne and eczema can affect the growth of your beard. These are the most common skin diseases that cause hair loss.

Treating these conditions may help you to grow a fuller beard but there are also some lifestyle changes you can make to improve your chances of growing a fuller beard.

Certain medications

Certain medications, such as antidepressants or anti-psychotics, can slow the growth of facial hair and even make it fall out. This is because some of these drugs cause hormonal imbalances that disrupt the normal balance of testosterone and DHT (the male sex hormone that causes hair to grow). Antihistamines are a type of medication that decreases the sensitivity of your skin and slows down skin regeneration. They're often used to treat allergies and colds; however, if you have a beard that's sensitive to sunlight, be sure to avoid taking antihistamines in order to prevent any further damage.

Beard dandruff

Dandruff is a common problem for men who grow beards. Why? Because the skin underneath your beard is being dry and flaky, which means dead skin cells are falling out. Beard dandruff can be caused by shaving against the grain or poor diet. If you have any of these problems, this could give you some tips on how to solve them!

Many factors can affect beard growth.

So what exactly can you do to make sure your beard grows as healthy and long as possible? First, keep in mind that some of the factors that can damage your beard are out of your control. Genetic predisposition and certain skin diseases, for example, may mean that you'll have to fight a little harder than others to get the same results.

If it's any consolation, though, there are plenty of things you can do on your end to make sure that your facial hair stays healthy and happy. Here are some tips:

  • Don't shave against the grain too frequently—it can cause ingrown hairs and irritation.

  • Eat a balanced diet with plenty of protein (especially fish), vitamins A and E (found in nuts like almonds), iron (red meat) and zinc (sardines).

  • If you're balding or already have patches where no hair grows at all due to male pattern baldness or alopecia universalis (a genetic condition affecting roughly 1% of men), consider shaving off more frequently than every day because this will allow new growth sooner rather than later.* Consider using an electric razor instead of traditional blades if possible; men who go this route tend not only grow thicker beards faster but also experience less irritation from shaving overall!


There are many factors that can affect your beard growth, but don’t worry! There are also a lot of things you can do to help improve it and keep your beard looking great. If you feel like something is preventing your hair from growing at its best, then check with a dermatologist to see what might be the cause.
