When you shave your hair does it grow back thicker

For something that billions of us do every day, there are plenty of myths around shaving. While we’re not averse to adding a little extra mystique to the ancient art of the shave, at Wilkinson Sword we’re in the business of making shaving straightforward. We’ve been experts in shaving for well over a century, so we’re better placed than most to clear up any misunderstandings that might crop up in bathrooms up and down the land.

One of the most common questions about shaving is what it does to your hair. Does it change the way it grows, paving the way for thicker or faster-growing hair to return in its place? It’s true that it can often seem like your hair is determined to defy whatever you do with a razor, coming back with more determination each time and occasionally making shaving feel like a futile exercise. But here, in black and white, are the facts about shaving and body hair…

Does shaving make hair thicker?

In short, no it doesn’t. Hair might appear to be thicker after you shave on any part of your body. When the hair begins to reemerge from your skin after shaving, the blunt end where the razor cut it can make it look thicker and darker, but it’s still exactly the same strand of hair that was there before, completely unchanged.

There are a few optical illusions that don’t help with the spread of this particular myth. One of them is down to the fact that the longer you don’t shave, the more the sun can make your hairs appear lighter and thinner. That means that when you do shave, the remaining hair is suddenly a lot more noticeable against the skin.

Another occurs because hair is naturally much thicker at the root than it is at the tip. That’s why brand new stubble looks more conspicuous when there’s no thinner hair to offset it. In reality, it’s impossible for hair thickness or colour to be impacted by shaving. Hair growth, on the other hand, is a different story…

Does shaving make hair grow back faster?

This one’s a little more complicated, because it can grow back faster but shaving’s got nothing to do with it – however, your genes have everything to do with it. Everybody’s gene pool determines the rate at which hair reappears, as well as the texture it develops. As a result of your genes, you might have more hair or thicker hair than other people, and it might grow back at what seems an exhausting rate. It’s not necessarily fair, but it’s science.

Does hair grow back faster on certain parts of the body?

Hair growth speed doesn’t just vary between people but between different areas of the body. Armpit hair tends to grow back around 50% faster than leg hair, and the same inconsistency applies right across the body – so you might find yourself engaged in a constant race to stay ahead of hair growth in some tricky spots.

Should I shave different parts of the body in different ways?

You can say that again. Every area of your body has a different type of hair – whether you’re keeping the downstairs region in check or tackling those pesky patches that sprout in unexpected places as you grow older. The key is to be equipped with the right tools and clued up on the right techniques for each. A well-practised, carefully honed head-to-toe grooming routine will keep you looking your best and stop your hair getting out of control – whatever speed or thickness it grows at.

It's time to face the facts.

High school is a time filled with learning—and we're not just talking about during lessons. But it turns out that some of the "facts" we've held onto as gospel since our school days are actually nothing more than myths. Take hair removal, for example. I can't have been the only one told that shaving would make my hair grow back even thicker and stronger.

But does it? Not according to Chloe Scriminger, head trainer at boutique salon chain Ministry of Waxing. Well, not exactly, that is. "Only the shaft of the hair is removed when you shave," says Scriminger. "This is the part of the hair that grows out of the epidermis (the skin's surface); the hair follicle is still in the dermis." She explains that because the follicle hasn't been removed it will still be nourished by blood vessels in the dermal papillae ensuring it remains healthy and strong. 

But that's not to say shaving doesn't make any difference to the hair that grows back. "After a shave, the hair all grows through together at the same time very bluntly, because it has been cut with a blade," says Scriminger. So while your regrowth may not actually be thicker or stronger, it can certainly feel like it. 

So what are the options if you're bored of stubble? Scriminger says waxing can be done when the hair shaft is at 6 millimetres, which is about 10 days to two weeks after shaving. When hair grows back after waxing, the new tip usually means it feels softer and finer than after shaving. 

For a more permanent removal solution, look to the laser: "It works by light converting to heat energy in the dermis and cutting off the blood supply to the dermal papillae ceasing the hair to grow," says Scriminger, and can show permanent results in six sessions.

Is shaving your head good for your hair?

That's a myth that persists despite scientific evidence to the contrary. Shaving has no effect on new growth and doesn't affect hair texture or density. Hair density has to do with how closely strands of hair are packed together. Older growth tapers out at the ends and lightens with exposure to sunlight.

How long does it take for shaved hair to grow back?

Shaving facial hair with a razor is a common practice to get rid of unwanted hair. It removes the hair just above the roots and preserves its ability to grow back. It usually takes two weeks to get your hair back after shaving. After then they grow at the pace of half an inch per month.

Why does my hair grow so fast after shaving?

The act of shaving does not make your hair grow back faster, your genetics do. Hair texture and regrowth are determined by your gene pool. Some people have more hair than others; some people have thicker hair than others; and, everyone's hair grows back at different rates.

Does plucking hair make it grow back thicker?

However, repeated ripping of the hair from its follicle via waxing or plucking (which is essentially the same thing, when you think about it) will make hair grow back thicker, darker and coarser… and frequently, more plentiful and faster to re-grow.
