Does Shaving Help Beard Growth: Myths and Facts

There is a common myth that shaving regularly can help promote beard growth, but there is no scientific evidence to support this claim.

Shaving only removes the hair that has already grown out of the follicle, and it does not affect the rate at which hair grows or the thickness of hair.

The growth of facial hair is primarily determined by genetics and hormone levels, particularly the male hormone testosterone. Testosterone levels play a significant role in determining the amount and thickness of hair that grows on the face.

Therefore, while shaving may help to maintain a neat and tidy appearance, it is unlikely to have any significant impact on the growth of your beard.

If you are looking to promote beard growth, you may want to focus on maintaining a healthy diet, getting enough sleep, and exercising regularly, as these factors can contribute to overall health and well-being, which in turn may support healthy hair growth.

How Shaving Affects Beard Growth

There are a lot of myths about the relationship between shaving and beard growth. One of the most popular is that shaving will make your beard grow thicker and faster.

However, this is not true. Shaving does not affect the rate at which your beard grows or the thickness of the hair. The only thing that affects these factors is genetics.

Understanding the Process of Shaving

Before delving into how shaving affects beard growth, it’s important to understand the process of shaving itself.

When you shave, you’re essentially removing hair that has already grown out of the follicle. This means that you’re not actually affecting the hair that’s still inside the follicle, which is responsible for determining the rate and thickness of hair growth.

Shaving Does Not Affect Hair Growth

Contrary to popular belief, shaving does not affect the rate at which hair grows or the thickness of hair. This is because hair growth is determined by genetics and hormones, not by the act of shaving.

While it may seem like your beard is growing back thicker or faster after a shave, this is simply an illusion caused by the fact that you’re cutting off the tapered end of the hair, which can make it appear thicker and coarser.

Lack of Scientific Evidence

Despite what some may claim, there is no scientific evidence to support the idea that shaving can help accelerate beard growth. In fact, most experts agree that there’s no way to make hair grow faster or thicker than it naturally would.

While there are some products on the market that claim to help promote beard growth, it’s important to take these claims with a grain of salt and to consult with a doctor or dermatologist before using any new products.

The Science Behind Beard Growth

For many men, the ability to grow a full, thick beard is a point of pride. But have you ever stopped to wonder about the science behind beard growth?

From hormonal influences to genetics, there are a number of factors that play a role in how your beard grows. In this article, we’ll explore the science behind beard growth and what you can do to encourage a healthy, full beard.

Hormones and Beard Growth

One of the biggest factors that influences beard growth is hormones. Specifically, testosterone is the hormone that’s responsible for the development of facial hair.

Testosterone is produced in the testes and adrenal glands and is responsible for a range of male physical characteristics, including body hair growth.

When it comes to beard growth, it’s important to note that testosterone alone isn’t enough to promote facial hair growth. Dihydrotestosterone (DHT), a derivative of testosterone, is also necessary.

DHT is responsible for the growth of terminal hairs, which are the thick, long hairs that make up a full beard.

Genetics and Beard Growth

While hormones play a major role in beard growth, genetics also play a significant role. The genes you inherit from your parents determine the density and pattern of your facial hair growth.

In other words, if your father and grandfather had full beards, you’re more likely to have one as well.

Interestingly, your genes also determine the color and texture of your beard hair. If your family has a history of red hair, for example, you may be more likely to have a red beard.

Similarly, if your family has thick, coarse hair, your beard may also be thick and coarse.

Causes of Slow or No Beard

For many men, a thick, full beard is a sign of masculinity and virility. However, not all men are able to grow a beard, or may find that their beard growth is slow and patchy.

In this article, we’ll explore the various causes of slow or no beard growth, and what you can do to address them.

Hormonal Imbalances

One of the most common causes of slow or no beard growth is hormonal imbalances. Testosterone and dihydrotestosterone (DHT) are the hormones responsible for facial hair growth.

If your body produces too little of these hormones, or if your body is unable to convert testosterone into DHT, you may experience slow or no beard growth.

The low levels of testosterone result in patchy or no beards.  Other signs that indicate low levels of testosterone are:

  • Erectile dysfunction
  • Increase in body fat
  • Tiredness
  • Mood swings


Another major factor in beard growth is genetics. Some men simply have genes that don’t allow for thick or full facial hair growth. If your father or grandfather had a patchy or sparse beard, you may be more likely to experience slow or no beard growth as well.

Poor Diet

Your diet can also play a role in beard growth. A diet that is low in nutrients such as protein, vitamins, and minerals can lead to slow or no beard growth.

Eating a diet that is high in processed foods, sugar, and unhealthy fats can also have a negative impact on beard growth.

Skin Issue (Alopecia Areata)

Research indicates that approximately 2.5 million individuals in the USA are afflicted with Alopecia Areata, an incurable autoimmune condition that weakens beard follicles, resulting in hair loss or shedding.

Various treatment options are available, including Rogaine (Minoxidil), Topical Immunotherapy, Corticosteroid Creams, Oral Immunosuppressants, and Dritho Scalp.


Stress can also impact beard growth. Chronic stress can lead to an increase in the hormone cortisol, which can interfere with the production of testosterone and DHT.

Additionally, stress can also cause hair follicles to enter the resting phase of the hair growth cycle, which can lead to slow or no beard growth.

Medical Conditions

Certain medical conditions can also impact beard growth. For example, thyroid disorders can interfere with the body’s ability to produce and regulate hormones.

Autoimmune disorders, such as alopecia areata, can also cause hair loss, including facial hair. If you suspect a medical condition may be impacting your beard growth, it’s important to consult with a healthcare professional.


Hair growth is influenced by geography as well. For example, individuals from the Mediterranean region tend to have bushier and thicker beards, whereas Chinese individuals often struggle to grow a complete beard.

Conversely, Caucasian men are often blessed with voluminous facial hair. Nonetheless, this factor has limited significance, as genetics and testosterone levels play a more crucial role in determining facial hair growth.

Get Yourself Familiar with Hair Growth Cycle

The hair growth cycle consists of four main phases: anagen, catagen, telogen and exogen. Each phase has a specific function and duration, and understanding these phases can help you understand how hair grows and how to care for it.


  1. Anagen Phase

The anagen phase is the active growth phase of the hair cycle, during which the hair shaft grows from the follicle.

This phase typically lasts between two to seven years, and the length of the phase determines the maximum length your hair can grow. About 90% of your hair is in the anagen phase at any given time.

  1. Catagen Phase

The catagen phase is a transitional phase between the anagen and telogen phases. During this phase, the hair follicle begins to shrink and detach from the hair shaft. This phase lasts about two to three weeks.

  1. Telogen Phase

The telogen phase is the resting phase of the hair growth cycle, during which the hair follicle is at rest and no hair growth occurs. This phase lasts about three to four months.

At the end of this phase, the hair shaft falls out and a new hair begins to grow in its place, restarting the growth cycle.

  1. Exogen Phase

The exogen phase is a natural part of the hair growth cycle and occurs after the telogen stage. It involves shedding hair from the scalp, which is often facilitated by washing and brushing. It’s common to lose between 50 and 100 hairs per day during this phase.

How to Accelerate Beard Growth?

Growing a thick and lustrous beard is a matter of pride for many men. However, not everyone is blessed with fast-growing facial hair. If you’re struggling to achieve your desired beard growth, don’t worry.

With the right techniques and tips, you can accelerate the process and achieve your dream beard in no time. Here are some of the most effective ways to accelerate beard growth:

  1. Maintain a healthy lifestyle

A healthy lifestyle is essential for promoting hair growth. Make sure to exercise regularly, get enough sleep, and eat a well-balanced diet rich in vitamins and minerals.

Nutrients like biotin, vitamin E, and protein can help stimulate hair growth and promote overall hair health. Make sure you intake:

  • Vitamin B6
  • Vitamin C
  • Vitamin E
  • Beta-Carotene
  1. Use beard oil

Beard oil is a popular product used by men to condition and moisturize their facial hair. It’s made from natural oils like jojoba oil, argan oil, and coconut oil, which help to soften and hydrate the hair, making it easier to grow.

Apply beard oil daily to keep your beard healthy and moisturized.

  1. Exfoliate your skin

Exfoliating your skin can help stimulate blood flow to your hair follicles, promoting hair growth. Use a gentle scrub to remove dead skin cells from your face and neck. This will also help to prevent ingrown hairs, which can slow down beard growth.

  1. Drinking Plenty Water

Not only hydration water also helps to grow facial hair rapidly.  Drinking plenty of water promotes blood circulation and this blood flow transfers oxygen to cells and tissues, resulting in enhancement of the overall health of your skin.

A good skin condition leads to good facial hair growth.

  1. Use minoxidil

Minoxidil is a topical medication used to treat hair loss. It can also be used to stimulate beard growth. Apply minoxidil to your beard area twice a day to promote hair growth.

However, it’s important to note that minoxidil can cause skin irritation, so make sure to follow the instructions carefully.

  1. Be patient

Beard growth takes time and patience. Don’t get discouraged if you don’t see results right away. Keep up with your beard care routine and be consistent. It may take several weeks or even months before you see significant growth.

The Right Way to Shave Your Facial Hair

Shaving is a fundamental part of most men’s grooming routine. However, many men struggle with shaving their facial hair, resulting in cuts, irritation, and discomfort.

In this article, we’ll provide a comprehensive guide on how to shave your facial hair the right way, using the proper techniques and tools.

Step 1: Prepare Your Skin

The first step in shaving your facial hair is to prepare your skin properly. This will help reduce the risk of cuts, razor burn, and other skin irritations.

  1. Wash your face: Use a gentle cleanser to wash your face and remove any dirt or oil from your skin. This will help prevent clogged pores and improve the overall effectiveness of your shave.
  2. Apply pre-shave oil: Pre-shave oil helps lubricate the skin and hair, making it easier for the razor to glide over your skin. It also helps protect your skin from the blade.
  3. Apply shaving cream: Shaving cream helps soften the hair and provide additional lubrication. Apply a generous amount of shaving cream to your face and neck, using a brush or your fingers to create a thick lather.

Step 2: Choose the Right Razor

Choosing the right razor is crucial for achieving a smooth and comfortable shave. There are two primary types of razors: electric and manual.

  • Electric razors: Electric razors are great for quick and easy shaves. They are also less likely to cause cuts or irritation. However, they may not provide as close of a shave as a manual razor.

  • Manual razors: Manual razors are available in two types – safety razors and cartridge razors. Safety razors are a classic option that use a single, replaceable blade. Cartridge razors feature multiple blades and are designed to provide a closer shave.

Step 3: Shave Properly

Now that you’ve prepared your skin and chosen the right razor, it’s time to shave.

  • Shave with the grain: Shave with the grain of your facial hair to avoid cuts and irritation. Shaving against the grain can cause razor burn and ingrown hairs.

  • Use light pressure: Use light pressure when shaving, allowing the razor to glide over your skin. Don’t press too hard, as this can cause cuts and irritation.

  • Rinse the razor frequently: Rinse the razor frequently to remove any hair or shaving cream buildup. This will help ensure a smooth and comfortable shave.

Step 4: After-Shave Care

After you’ve finished shaving, it’s essential to take proper care of your skin to avoid irritation and discomfort.

  1. Rinse your face: Rinse your face with cool water to remove any remaining shaving cream or oil.
  2. Apply aftershave: Aftershave helps soothe and protect your skin, reducing the risk of irritation and redness.
  3. Moisturize: Moisturizing after shaving helps keep your skin hydrated and prevent dryness or flakiness.
