The Most Common Haircare Myths We’ve Totally Fallen For

But the good news is that it could grow back less gray. According to Marie Claire, “This is because melanogenesis (the process by which hair follicles make the pigment that gives hair its color) is not totally consistent from hair to hair.” This doesn’t give you permission to go pulling all your gray hairs out, though!

5. Stress can turn your hair gray — so you better chill.

The scientific-jury is still out on this one. We know, we know — that year you were super stressed out was the same year you found your first few grays. Yeah, us, too (and every single president in office).

Apparently, going gray is entirely based on genetics. According to Scientific American, stress hormones could anecdotally generate more gray hairs, but there’s no observable, established direct link between the two.

In short, they say, “scientists are beginning to gather clues that stress can hasten the graying process, but there is no scientific evidence demonstrating a cause-and-effect relationship.” We beg to differ!

6. Added oils are bad for greasy hair.

Although it feels a bit counter-intuitive, oils don’t add oiliness to already-oily or greasy hair. In fact, the added oils can be really good for you. (It’s the same with skin-care, by the way).

People with oily skin can totally use facial oil, something that derms have been trying to tell us for a while.  According to Marie Claire, the oils actually penetrate the hair shaft, making it healthier from the inside out.

Some of the best hair oils include argan oil, which can be used for dry and frizzy hair, coconut oil for all hair types, almond oil, which is a favorite among people who have dandruff or an itchy scalp, and Abyssinian oil, which is hydrating for fine hair.

7. If you leave your hair alone, it will self-clean.

Sorry to burst your bubble, but this isn’t true. Everyone needs to wash their hair from time to time — and of course, this differs per person and per hair type.

But there are people who are part of the “no-poo” movement, which argues against using traditional washing products for hair. The no-wash movement and its followers skip the condition and shampoo in favor of natural products like vinegar, egg, and water. Lots of people love this approach, while others do not. 

The thing is, shampooing isn’t too harmful. According to Bustle, dermatologist Dr. Nicole Rogers, the assistant clinical professor of dermatology at Tulane University, said, “For the average person with healthy, untreated hair, there is no evidence that the simple act of shampooing, so long as it is with the appropriate ingredients for your hair, will cause damage.” Just look for good-for-hair shampoos, and shampoo only as often as your hair needs it.

8. But towel drying your hair is totally cool, right?

The American Academy of Dermatology has determined that vigorous hair drying with the help of a towel is a big no-no. That’s because the hair is at its most vulnerable when wet and can break far more easily — especially if it’s being shaken about and pulled by a cotton towel.

9. You should be brushing your hair with 100 strokes a day.

This one is just categorically false. First off, who came up with this arbitrary number? It doesn’t even make any sense.

Second, while it’s true that brushing your hair can help distribute the naturally occurring hair oils, it’s not necessary to do so to make it happen.

For one, it can make certain hair types super frizzy (was this rule invented by a straight-haired gal?), it’s tiring, and it can cause breakage and cuticle damage. Plus, people with certain hairstyles don’t need to brush their hair daily at all.

10. Brushing your hair while in the shower is a good idea, right?

Attention all curlies: You should listen in here. According to Naturally Curly, some people with very curly hair like to brush while in the shower — but this can be particularly harmful to your hair.

As they say, “Hair that is damaged, already fragile, or in a compromised state becomes even more prone to breakage when wet.”

If you do have to brush your hair in the shower, use a super wide-toothed comb, and don’t do it while the water is running right on the hair.

11. You need to switch your shampoos all the time.

A lot of people argue that switching your shampoo out can keep your hair from getting used to certain shampoos. But this just isn’t true.

If you do need to switch your products, it’s most likely due to seasonal or environmental changes, not the hair itself. For example, in the wintertime, our hair gets way, way dryer.

So, the next time you’re shopping, don’t instinctively buy the next shampoo brand you see. You can afford to wait a little longer.

12. Washing your hair under cold water makes it extra shiny.

Sort of. According to Atelier Emmanuel, “Technically, cold water will cause the hair cuticle to lay flat; this creates smoothness and some shine. However, any benefit this brings is negated if you apply any heat, such as with a blow drier or flat iron.

They continue to explain that, “if you wanted to get the marginal benefit of rinsing with cold water, you would also have to air dry your hair to maintain it.”

But what about dying your hair if you’re breastfeeding? There’s actually not much data, but the general idea is that not much of the chemical enters into the bloodstream.

This is good news, but lots of people don’t want to chance it. For that reason, many turn to organic, all-natural dyes. It’s important to note that the American Pregnancy Association recommends waiting to dye your hair until your second trimester. The first trimester is a pretty delicate time.

14. You have to rinse out every drop of conditioner.

Lots of people were told growing up that you needed to be thorough when rinsing out your conditioner. Turns out, that’s actually not the case.

According to Reader’s Digest, you should probably leave some of that conditioner in your hair! As Doug Martucci, Creative Director at PRORITUALS says, conditions helps protect your hair, so leaving some in as a good idea.

Some people are afraid that it’ll make their hair oily, but it usually won’t. So, just go for it. You can also opt for a leave-in condition, too.

15. White flakes mean you have dandruff.

Okay, so people think of dandruff as white flakes, but seeing these little specks in your hair doesn’t automatically mean you have dandruff.

In fact, white flakes can come from having a dry, super-thirsty scalp in deep need for exfoliation. It can also happen when there’s a major temperature shift due to the changing of seasons. If this is the case, use a scalp-loving hair mask or be sure to use extra condition.

Whatever hair care means to you is what you should be doing. If that means skipping the shampoo and getting regular cuts, cool. If that means making DIY scalp treatments and using sulfate-free products, go for it.

The problem with so much of the beauty and hair-care information out there is that it often doesn’t account for personal style, genetics, environment, culture, or, you know, financial ability. Not everyone can afford to get a professional blow-out weekly, while some people just don’t want to rock long locks. Hair is personal. Hair is part of our identity. And what works for you doesn’t always work for others. Your hair is a part of you, and it deserves lots of love!
