If You Shave Your Arms Does It Grow Back Thicker

Explanation of Hair Growth

Hair Growth

Before we dive into the myth of whether shaving your arms will make your hair grow back thicker, let’s first understand the basics of hair growth. Hair is made up of a protein called keratin and is produced by hair follicles located in the skin. Hair growth occurs in three phases: anagen (growth), catagen (transition), and telogen (resting).

During the anagen phase, which lasts for several years, hair actively grows and is nourished by blood vessels in the scalp. The catagen phase is a short transitional phase where hair growth slows down, and the follicle shrinks. The telogen phase is a resting phase where the hair stops growing and eventually falls out, making room for new hair to grow.

The length of each phase and the rate of hair growth can vary depending on genetics, age, hormones, and other factors. Generally, hair grows at a rate of about 0.5 inches (1.25 cm) per month, and the average person has about 100,000 hair follicles on their scalp.

Now that we understand the basics of hair growth let’s explore the myth of whether shaving your arms can affect hair growth.

Myths about Shaving

In the sphere of hair removal, the act of shaving has long been steeped in a tapestry of misconceptions and fallacies. Among these, one of the most pervasive is the notion that shaving body hair – be it on one’s arms, legs, or otherwise – can have the effect of inducing a more accelerated or thicker regrowth of hair. This is a tenet that has been handed down through the ages, its perpetuation buoyed by a variety of misrepresentations, including the tendrils of popular culture and the propagation of information that is often less than accurate.

Yet despite the persistence of this myth, the truth is that shaving, contrary to popular belief, has no impact whatsoever on the rate or volume of hair growth. What it does do is merely cut hair at the surface level, an action that has no bearing on the hair follicle itself or its capacity to sprout hair. The perception that hair might regrow at a more accelerated pace, or with greater heft, is purely an illusion – a product of the fact that the hair that was shaved has a blunt, rather than the tapered, tip. This difference in texture is often perceived as a greater thickness or coarseness in the hair that grows back.

The question then arises: why do so many people continue to believe that shaving has an impact on hair growth? One possible explanation is that the newly grown hair that emerges after shaving can feel coarser or pricklier due to its blunt tip. Another reason, as noted earlier, is that the new hair might appear to be darker or thicker, again because of its blunt end. Yet a third explanation lies in the phenomenon of “terminal hair,” in which the growth of hair becomes thicker and darker as it reaches maturity. This can create the impression that hair is growing back more.

Science behind Shaving

The idea that shaving makes hair grow back thicker or faster is a persistent myth that has been debunked by scientific studies. Shaving does not change the thickness or color of the hair that grows back, but it can affect the hair’s appearance and texture temporarily.

When you shave your arms, you are cutting the hair at the surface level, which does not affect the hair follicle or its ability to grow. However, there is a phenomenon called “terminal hair,” which can make it seem like hair is growing back thicker after shaving. Terminal hair refers to the type of hair that is thicker and darker, such as the hair on your scalp or eyebrows. This type of hair is not affected by shaving because it is already at its maximum thickness and color.

When you shave your arms, you might notice that the hair that grows back is darker or thicker, but this is only because the hair was cut at the surface level, creating a blunt tip. Over time, the hair will grow out and return to its natural thickness and color.

In fact, scientific studies have shown that shaving can actually make the hair appear thinner and softer over time. This is because shaving can gradually weaken the hair follicle, causing the hair to grow back with a softer texture.

Overall, the science behind shaving and hair growth is clear: shaving does not make hair grow back thicker or faster. While the hair that grows back might appear darker or thicker due to the blunt tip, this is only a temporary effect, and the hair will return to its natural thickness and color over time.

Tips for Shaving

Shaving your arms may not induce the growth of thicker hair, however, it is paramount to implement appropriate shaving techniques to circumvent skin irritation and the formation of ingrown hairs. Here are some efficacious tips to assist you in shaving your arms and body hair in a proper manner:

Commence with Exfoliation: Before initiating the shaving process, it is imperative to exfoliate your skin to eradicate any dead skin cells or debris that could potentially obstruct your razor. Make use of a gentle exfoliating scrub or a loofah to aid in preparing your skin for shaving.

Utilize a Sharp Razor: It is fundamental to ensure that your razor is sharp and pristine before shaving. A blunt razor can be a major culprit behind skin irritation and may amplify the probability of ingrown hairs.

Application of Shaving Cream: Before shaving, apply shaving cream or gel to your arms to lubricate your skin and thwart razor burn. Avoid using soap, as it can dry out your skin, elevating the likelihood of razor burn.

Shave in the Direction of Hair Growth: While shaving, ensure that you move the razor in the direction of hair growth to evade skin irritation and the onset of ingrown hairs. If you need to shave against the grain to get a closer shave, make certain to apply extra shaving cream or gel to avoid irritation.

Rinse and Moisturize: Following the shaving process, rinse your skin with cool water to eliminate any remaining shaving cream or gel. Gently pat your skin dry and apply a moisturizer to soothe and hydrate your skin.


In conclusion, the myth that shaving your arms will make your hair grow back thicker or faster is just that – a myth. Scientific studies have shown that shaving does not affect hair growth, but rather only affects the hair’s appearance and texture temporarily.

While shaving your arms and body hair can be a personal choice, it is important to follow proper shaving techniques to avoid skin irritation or ingrown hairs. Exfoliating, using a sharp razor, applying shaving cream, shaving in the direction of hair growth, and moisturizing after shaving can all help ensure a smooth and irritation-free shave.

So, feel free to shave your arms and body hair without worrying about the hair growing back thicker or faster. And remember, personal grooming choices are entirely up to you, so do what makes you feel comfortable and confident in your own skin.
