Hair Growth After Shaving: Separating Myth from Fact

You've probably heard that shaving hair makes it grow back thicker. It's something many of us get told as kids, and end up believing for our whole lives. But is there any evidence for this claim? And if it's not true, why is it so commonly believed? Let's take a look at the truth of how shaving affects your hair growth.

Does Shaving Make Hair Grow Back Thicker?

A lot of people believe that shaving makes your hair grow back thicker. It isn't true, but it's a persistent myth people continue to repeat to this day. 

Why? Because shaving can make hair look thicker. Shaving cuts hair off at the surface of the skin and doesn't affect the follicle underneath, so it can't change the way hair grows. But the change in appearance it can cause has led to this idea.

Ultimately, it's a visual trick. Shaving is not going to make your hair grow back any thicker than it was before, but it might make it appear that way.

Why Hair Looks Thicker After Shaving

Blunt Hair Tips

When hair grows naturally, it tapers to a point. But when you shave, you cut straight across the hair, leaving a blunt edge.

That's why stubble feels as rough and scratchy as it does. It also makes stubble look thicker than uncut hair. The diameter of the hair shaft doesn't change, but by losing the fine tip, it can look thicker.

Contrast Against Skin

When you shave your skin, you make it more visible. If your skin is lighter than your hair, that increases contrast. As the hair starts to grow back, it will be more noticeable against the exposed skin. This is especially noticeable on the scalp, face, and other high-visibility areas.

Early Growth Phase Is More Noticeable

Short hair tends to stand straight up. As your hair gets longer, it bends and lies flat against the skin, which makes it look less dense. Bristly stubble is short and stiff, which makes it highly visible, and can make it look like it has grown out heavier.

What Actually Determines Hair Growth?

So if shaving doesn't make your hair grow thicker, what does? Ultimately, hair growth comes down to some pretty fundamental biology.

Genetics

The biggest thing that determines how your hair looks and grows is genetics. The genes you inherit from your parents determine your hair texture, color, and the thickness of individual strands of hair. 

If thick hair runs in your family, there's a good chance you'll have it too, and shaving won't make any difference. 

Hormones

Genetics play a major role, but our hair changes throughout our lives as a result of hormones, too. Androgens like testosterone and DHT influence hair growth patterns and change the way your hair grows over time. For example, common male pattern baldness is linked to testosterone and DHT. So, the same hormones that cause beard growth in puberty can cause you to lose hair on your head.

Age & Health

As we age, our bodies change. That includes our hair follicles. With time, they may shrink, slow down, or stop producing hair altogether. This has nothing to do with shaving, though. It's just a natural part of growing older.

Does Shaving Affect Hair Growth Long-Term?

In a word, no. Shaving your face, your head, or any other part of your body has no long-term effect on hair growth.

It won't make your hair grow back thicker. Nor will it cause you to lose your hair faster.

To permanently change hair growth, something needs to affect the hair follicle, which lies below the skin. That's why hormones and medication can affect hair growth, but shaving can't.

Even if you shave your head daily, your hair growth pattern remains the same as it would be otherwise.

The Benefits of Shaving (Without the Myths)

Shaving isn't going to make your hair any thicker than it would otherwise be. But it does offer real advantages in other areas.

Cleaner Look

For a sharp, defined look, a freshly shaved scalp or face is hard to beat. A clean shave from a quality shaver, like the Groomie® BaldiePro™ Head Shaver Kit, creates a polished appearance that works well for both professional and casual settings.

Easier Maintenance

Shorter hair requires less styling. Shaving can simplify your grooming routine, saving you hours of prep time over the long term.

More Control

Shaving gives you more control over your look. It lets you deal with uneven growth or patchiness so that you can have a consistent appearance.

Comfort and Hygiene

Lots of people find a clean-shaven scalp feels cooler and more comfortable, especially in the heat of summer.

Frequently Asked Questions

How Quickly Does Hair Grow After Shaving?

Human hair grows at around 0.014 inches a day. That’s 0.1 inches a week. On your scalp, noticeable stubble can start to appear within one to three days after shaving. Facial hair becomes visible even sooner, with the famous 5 o'clock shadow starting to show on some people within a day.

Why Does Shaved Hair Feel Rough?

Shaving cuts straight across the hair, leaving a blunt edge instead of the natural tapered tip. That blunt edge feels sharper and rougher than uncut hair. As the hair grows, the texture softens and feels less rough.

Can Shaving Cause More Hair Follicles to Develop?

No. The number of hair follicles you have is determined before you're born. As you age, hair follicles may stop producing, but there’s no way to grow new hair follicles.

Is Shaving Better Than Waxing For Hair Growth Control?

Shaving cuts hair at the surface. Waxing pulls it out at the roots. Neither method affects the hair follicle itself. Waxing may delay regrowth more than shaving, but neither method will change how thick your hair grows.

Shaving Does Not Change Hair Growth or Hair Thickness

Shaving changes the way you look, but it won't change the way your hair grows. It can make it look as if your hair is growing back thicker, but it won't change the follicles that determine your hair growth.

For a clean, controlled look, shaving is one of the simplest and most effective grooming choices you can make. The Groomie® BaldiePro™ Head Shaver Kit gives you a fast, comfortable way to maintain your style without making permanent changes to your hair.
