What causes poor beard growth?

A healthy beard is an important part of anyone's appearance, but many men suffer from poor beard growth. If you're a man who can't grow a thick, luscious beard no matter how hard you try, it's likely that your inability to do so is caused by some form of hormonal dysfunction. Fortunately, there are ways to fix this problem without resorting to medications or expensive treatments. Here are the most common reasons why guys' facial hair doesn't grow as fast as they'd like:

Testosterone and beard growth

Testosterone is a male hormone that helps your body grow hair, including facial hair. As you get older, your testosterone levels decrease and this can cause poor beard growth.

Low testosterone levels are also common in men with diabetes or thyroid disease, as well as those who follow a poor diet.

Insulin resistance and beard growth

Insulin resistance is a condition that occurs when your body is unable to process insulin properly. Insulin is a hormone that allows glucose (blood sugar) to enter your cells, where it can be used for energy or stored as fat.

When this happens, your pancreas secretes more and more insulin to try to get the job done--and because of this excess secretion, there's not enough left over for other processes like maintaining healthy hair growth on your face. The result? You may notice patches where no hair grows at all!

There are several factors that could contribute to poor beard growth: diet, genetics and lifestyle choices all play an important role in determining how thick or thin your facial fuzz will be. But one thing we can rule out right away is whether or not you're eating too many carbs--because while refined carbohydrates certainly aren't good for anyone's waistline (or health), they won't actually make it harder for you grow facial hair either!

Stress and beard growth

Stress can cause hair loss and it can also cause your facial hair to grow in patches and even at unusual places. If you're stressed out, your body may not be able to produce the right hormones needed for healthy growth of facial hair.

Stress can also lead to an increase in testosterone levels which is another reason why some guys don't grow much facial hair (or have patchy beard growth).

Genetics and beard growth

Your genes play a big role in determining how much body hair you have, and how quickly it grows. A man's beard will grow about twice as fast as the hair on his head, but there are some men whose beards grow even faster. This is because they have more hair follicles than others, which means that their bodies produce more testosterone (the hormone responsible for hair growth).

The thickness and texture of your facial hair depends on several factors including:

  • Your genetic makeup

  • How old you are when puberty begins (androgens like testosterone affect this)

Nutrition and beard growth

If you're looking to see a difference in the thickness of your beard, then it's important that you make sure that your diet is balanced and healthy.

In order to grow a healthy beard, there are certain nutrients that are required. These include: omega 3 fatty acids (found in fish oil), zinc (found in oysters), B vitamins (found in eggs) and protein-rich foods such as meat or beans. It's also important not to overdo things--too much caffeine or alcohol can affect hormone levels which may prevent hair growth altogether!

Thyroid disease and beard growth

A thyroid condition can be caused by genetics or environmental factors. If you are diagnosed with a thyroid condition, your doctor may recommend that you take medication to regulate the hormone levels in your body. This will help prevent one of the most common causes of poor beard growth: dry skin and hair loss.

Poor circulation to the face and beard growth

Poor circulation to the face and beard growth

Poor circulation to the face and hair loss can be caused by a number of things. Smoking, diabetes, high blood pressure and heart disease are some of the most common causes. Smoking is especially dangerous because it reduces oxygen supply to all parts of your body, including your beard follicles. The effects of smoking on facial hair growth are not just limited to these physical factors; it's also known that smoking may damage testosterone levels in men which leads to slower beard growth as well as other male characteristics like balding or greying hair at an early age (1). In addition to these lifestyle choices that affect facial hair growth negatively - there are certain health conditions which directly cause poor circulation around the face area:

Poor beard grow is often caused by either a lack of testosterone or insulin resistance.

If you've been struggling to grow a full beard, the problem may be related to your testosterone levels. Testosterone is an androgenic hormone that affects the development of male characteristics. It's produced in the testicles, but also in the adrenal glands--and it's responsible for beard growth.

If you have low testosterone levels (or if they're not being used properly), this can lead to poor beard growth or even lack of facial hair altogether. The good news? If you've got a case of low T, there are plenty of ways to boost it naturally so that you can finally sport those stubble scruffs without feeling self-conscious about looking like an adolescent boy all over again!


While there are many factors that can affect your beard growth, it's important to remember that the most important one is your own genetics.
