Myth: I Canâ€™t Train My Hair to Do Something
Hair can totally be trained to grow a certain wayâ€”but itâ€™s going to take some time and consistent manipulation, says Reslan. â€œThe follicles in our scalp are typically angled in a position influenced by gravity, making the hair grow out and down,â€ she explains. â€œYou can alter these growth directions by maintaining consistent and gentle tension in the desired direction.â€ That means regularly combing your hair in the direction you want it to go and securing it.
If youâ€™re looking to switch your part, Reslan notes that itâ€™s crucial that you put it where you want it once you hop out of the shower (so, when itâ€™s still wet) and set it using styling gels, or a ponytail holder if your hair is long enough. You can also blowdry and set the new look. â€œ Over-time, the repeated motions can slowly start to alter the way the hair grows out,â€ she says.
Myth: Shaving Will Make My Hair Grow Thicker or Faster
Since hair is essentially protein and keratin, there's no way for it to communicate with your body. So while some people believe that shaving causes hair to grow back faster or thicker, this is not possible since your body has no way of knowing whether you shaved or not. â€œAny hair that is shaved appears to grow in thicker simply because the ends of the hair are cut straight across, creating a more blunt and thicker appearance compared to a new cycle of hair growing in and starting thinner and naturally more pointed,â€ says Reslan.
Myth: Getting Frequent Haircuts Will Make Hair Grow Faster
Getting your hair cut more often will not make it grow any faster. It does, however, help with breakage, which can make it seem like your hair is growing at a more rapid rate. â€œA trim only affects the ends of the hair strand and has no biological effect on the hair,â€ says Friese. â€œBut a healthy trim of split ends or damaged hair will help it become longer because it wonâ€™t be breaking off at the ends.â€
Myth: You Have to Shampoo Your Hair Daily
This isnâ€™t true as long as youâ€™re following the â€œgolden rule,â€ as Reslan calls it. â€œThe golden rule of shampoo frequency is to use the correct products based on your washing habits,â€ she says. She explains that those who might prefer to shampoo less frequently should use a clarifying shampoo to maintain a healthy scalp environment.
Myth: Plucking Gray Hairs Will Make More Grow Back
First thingâ€™s first: Gray hair is the result of a combination of stressors on the hair follicles (e.g. inflammation, stress, etc.), explains Reslan. â€œAlthough plucking canâ€™t be fully responsible for creating another gray hair, the stress caused on the scalp from the plucking itself can perhaps increase the inevitability of another hair follicle losing its pigment,â€ she says.
Myth: Hair Can Turn Gray Overnight
If you've read the answer to the above myth, you should already be able to figure out the answer to this one. Remember, hair is considered â€œdead,â€ Friese reminds us, so it canâ€™t actually turn colors overnight. â€œAn existing pigmented strand of hair can not turn gray, rather the same strand would continue to grow in without pigment at some point,â€ adds Reslan.
Myth: Growing My Hair Longer Will Hide My Hair Loss
Fact: Actually, in almost every circumstance, growing hair longer makes the thinning and baldness appear much more noticeable. â€œThe longer your hair is, the more it weighs and pulls down on the root of the hair in a manner that can expose the scalp more,â€ says Reslan. â€œThe appearance of thicker hair requires a length that is able to maintain a style that appears full throughout the mid- length to ends and well as maintaining weightless volume at the roots.â€
Myth #8: Shampoo Will Make My Hair Grow Faster
Picking the right shampoo can help you reach your hair goals. â€œSome shampoos can encourage the hair to stay in the anagen phase of hair growth longer and may help hair grow a bit faster,â€ says Friese. Some shampoos also help improve your scalpâ€™s microbiome, â€œensuring long-term quality hair growth,â€ adds Reslan.
Myth #9: Hair Loss Comes from My Mother's Side of the Family
Hair loss canâ€™t be attributed to a specific parent. â€œThe most common kind of hair loss androgenetic alopecia (pattern baldness) is caused by a genetic predisposed sensitivity to a hormone called dihydrotestosterone (DHT),â€ says Friese. â€œThis can be seen on both the maternal and paternal side of families.â€
Myth #10: Wearing Hats Can Prevent Hair Loss
On the contrary, wearing hats can cause hair loss if itâ€™s both too tight and worn very frequently. â€œTight hats can cause friction on the hair which can break it at the follicle which will give the illusion of hair loss,â€ says Friese. â€œThe friction may also irritate or damage the follicles which can eventually cause hair loss.â€
Myth #11: Dandruff Is Caused by Dry Scalp
According to both Friese and Reslan, there are a number of reasons why someone might have dandruff. â€œDandruff is usually caused by fungal infections of the scalp, too much oil secretion and/or sensitivity to hair products,â€ says Friese.
Dandruff can also occur on dry or oily scalps. â€œIn most cases, a dry flaky scalp can be caused by use of harsh cleansing ingredients in shampoos combined with over-washing,â€ says Reslan. â€œOily flakes on the scalp are typically a sign of inadequate cleansing of the scalp from either infrequent shampooing or the use of gentle cleansing shampoos that are incapable of sufficiently cleansing the scalp.â€
