Understanding Hair Myths: What Science Says

Alright, folks, let’s chat about hair. It’s something everyone deals with daily, yet the world is full of baffling hair myths and too-good-to-be-true miracles you hear from friends, family, sometimes even strangers or our corner barber. We all want that silky mane and Instagram-worthy locks, but amidst all the advice, how can you tell what’s gold and what’s fool’s gold? Today, we’re getting to the heart of debunking common hair myths with solid scientific explanations. Grab a coffee, kick back, and let’s unravel some hair truths.


The Yolk and the Follicle: Eggs for Breakfast, but Do They Work for Your Hair?

You might have heard about the classic hair mask made of raw eggs. Supposedly, slathering this on will have your hair shiny and full of life. But, hold on a second. Here’s what’s really going down.

Eggs are rich in protein, no question there, and yes, your hair’s made up mostly of protein called keratin. That’s probably where this whole idea took root. But is plopping this breakfast classic on your head doing what you hope? According to science, your hair might not re-absorb proteins in the way skin might soak up creams. What these eggs can do is coat the hair making it temporarily smoother and shinier. It won’t fundamentally repair or strengthen your hair, though.

So the bottom line is this – if you enjoy the occasional egg trick for quick shine, go for it. But don’t get your hopes pinned on it for deep nourishment or repair.


Trimming Hair: Shortcut to Faster Growth or Just a Neat Trick?

Here’s a myth that’s bandied about quite a bit, usually followed by a friend demanding a trim. Cutting your hair regularly makes it grow faster, right? Turns out, it’s more about appearance than science.

The fact is, trimming doesn’t influence the speed at which your hair grows. This is determined by genetics and your overall health. However, regular cuts prevent split ends, reducing breakage. This means your hair appears fuller and healthier, making it look like it’s growing faster when actually, it’s breaking less.

Make trimming a part of your routine so your locks stay neat and breakage-free. A modern twist on “look good, feel good”, don’t you think?

Cold Water Rinse: Does It Really Seal the Deal?

Cold water closes hair cuticles, making hair shinier—how true is that? Science speaks: While cold water might make hair appear less frizzy for a bit, it doesn’t permanently seal or smooth cuticles.

A gentle rinse with cooler water can indeed help minimize damage from super-hot showers, though. It’s less shock and awe, more of a gentle hug to your strands. Give it a breezy try, just don’t shiver if it’s winter! Regular conditioners and serums still pack more punch for sealing moisture.

Gray Hair: To Pull or Not to Pull?

Ah, the age-old debate—if you pluck a gray hair, do two more come to its funeral party? Rest easy: Science torpedoes this notion. Each hair follicle, gray or otherwise, operates independently. You won’t spawn more gray strands by plucking one, though it’s best to avoid unnecessary plucking to prevent follicle damage.

Gray hair is mostly about genetics. Embrace it, if that’s where you’re at, or touch up as needed.

Grease Paint: Does Oily Hair Need Less Conditioner?

For those with oily or greasy hair, skipping conditioner might seem logical. But this myth needs a second look. Greasiness is more about oil production from the scalp—not the hair itself.

Use conditioner focused on the hair shafts, not the scalp, where oil collects. Slip-n-slide morphs into manageable buoyancy. And if you’ve let go of conditioner altogether fearing oils, rethink—your strands need that moisture.

Hair “Adapting” to Products: Haircare or Skincare Buzzword?

Ever felt that your favorite shampoo suddenly stops working its magic? Some say your hair “adapts,” but the reality is more technical than that.

Build-up is a legitimate issue, mostly from silicones, parabens, and left-behind residues from your everyday products. Switching things up every so often isn’t about your hair changing; instead, it’s a signal to clarify or reset. Alternate between silicone-free and clarifying shampoos, and keep things fresh for your follicles.

Brush a Day Keeps the Bad Hair Away?

“Brush a hundred times to get silky hair!” might be something your grandma swore by. But are those bristles more bane than boon for your hair’s health? Over-brushing can lead to unnecessary friction, damage, and hair breakage.

Gentle detangling is the key here. A wide-tooth comb or a gentle brush can help to distribute natural oils and minimize tangles. Be kind to those knots—don’t declare war on them.

Hard Truth About Hard Water

If you live in an area with hard water and you’re aching for softer locks, you might notice your hair acting up—drier, duller, harder to manage. The minerals in hard water can build up, making your hair a grooming nightmare.

You’ve got a couple of weapons here. Clarifying shampoos combat mineral buildup. Alternatively, a water softener takes out the culprit at its source.

Shampoo Frequency: How Much Is Too Much?

How often should you actually shampoo? This depends more on personal lifestyle and hair type than a one-size-fits-all rule. Daily washers might strip precious oils if not careful. Then there’s the thrice-weekly team—they aim to balance cleanliness and moisture.

Both strategies work, as long as you’re dialed into what makes your hair feel best. Understand what speaks to your scalp and strands. Factor in exercise, oiliness, style maintenance—you’ve got a formula unique to you.


Surrounding Stressors: A Lesser-known Factor

Can stress make your hair fall out or turn gray? Unpacking a bundled myth here that’s part reality.

hair-myths-3

Intense stress might expedite a hair cycle known as telogen, basically an early push to shed and regrow. And while stress-related going gray isn’t precisely documented, stress might exacerbate the issue if predisposed to gray hair.

So, stress does play a role, mildly complex, yet having more open doors for relaxation—meditation, exercise, chill-out zones—could indirectly benefit your hair more than you’d think.


Diet: Feed Your Hair Right

Let’s circle back to the kitchen for a science-backed myth-buster. What you eat can impact your hair’s health. Proteins, vitamins, healthy fats—they nourish not your soul alone, but your strands too.

Biotin, vitamin E, and iron are big players in the hair game. Not about overnight miracles—more like a game plan for long-term investment in hair health.

Extensions and Hair Health: A Cautious Approach

Some rumors warn extensions will damage your hair beyond repair. While heavy or improperly installed extensions can lead to tension and breakage, they’re not all bad if done correctly.


Professional installation, gentle maintenance, and breaks to let your scalp breathe can keep the integrity of your hair intact. Enjoy those volume boosts wisely.

Frequently Asked Questions

Does getting a trim make your hair grow faster?

No, getting a trim does not make your hair grow faster. Trims only deal with the ends of your hair and do not affect the rate of hair growth, which is determined by the roots. However, trims can make your hair look thicker and healthier[1][5>.

Does washing your hair every day cause hair loss?

No, washing your hair every day does not cause hair loss. Washing your hair daily only removes hair that has already fallen out. Hair loss is more related to internal factors such as scalp problems, genetics, and emotional stress rather than external factors like washing frequency[2][5>.

Does shaving your head make your hair grow faster and thicker?

No, shaving your head does not make your hair grow faster or thicker. The appearance of thicker hair after shaving is due to all the hair being cut to the same length. Hair growth and thickness are influenced by internal factors such as diet, genetics, and overall health[1][5>.

Does shampooing your hair make it shed more?

No, shampooing your hair does not make it shed more. Hair sheds naturally, and shampooing simply collects the shed hair in one place, making it more noticeable. Keeping your scalp clean and managing stress can help reduce shedding[1][2>.
