The internet has ruined hair advice

There is almost no category more messy right now than hair.

Everyone is suddenly an expert. Your friend who discovered rosemary oil 6 business days ago is giving scalp advice like she completed a fellowship. TikTok wants you to believe your hair is thinning, your part is widening, your ends are dead, your follicles are clogged, and the only path forward is a 17 step routine featuring a scalp serum, a detox scrub, a bond repair mask, a boar bristle brush, a silk bonnet, and emotional resilience.

Meanwhile, half the people spiraling about hair loss actually have buildup or breakage or stress shedding or an inflamed scalp they’ve been ignoring while panic buying another miracle tonic in a frosted glass bottle.

Hair advice online has officially lost the plot.

So let’s do what the internet rarely does: separate fact from fiction:

“You shouldn’t wash your hair every day.”

Fiction. Or at least way too simplistic to be useful.

Daily washing is not inherently bad. If you have an oily scalp, fine hair, work out often, or pile on dry shampoo, washing more often may actually be the healthier move. A scalp sitting under layers of oil, sweat, residue, and buildup is not some sacred ecosystem you need to preserve at all costs.

What matters more is whether your shampoo is too harsh, too stripping, or just wrong for your scalp.

My take: stop following scalp advice written by someone with a few strands of dry, non-oily hair and pretending it applies to everyone.

“Topical products can reverse thinning hair.”

Fact.

Some topical products really can help. Minoxidil is still the gold standard over-the-counter option and actually has data behind it. There’s also growing interest in ingredients like rosemary oil, peptides, and caffeine.

But “thinning hair” is not one little straightforward problem. Stress shedding is different from androgenetic hair loss. Breakage is different from hormonal thinning. A neglected scalp is different from low iron. If you don’t know what kind of problem you’re trying to solve, your little serum journey is mostly performance art.

My take: some topicals work. But they work a lot better when they’re attached to an actual diagnosis.

“Silicones are bad for hair.”

Fiction.

Silicones have been turned into a villain ingredient. Are some silicones heavy for certain hair types? Sure. Can some formulas create buildup if you never wash properly and keep layering products like your ends are entering battle? Also yes. But the blanket statement that silicones are “bad” is lazy.

A well formulated product with silicones can help with frizz, slip, shine, and protection…especially if your hair is dry, porous, color treated, or heat styled. The issue is not the ingredient existing. The issue is whether the formula suits your hair and whether your scalp is actually being cleansed.

My take: I’m begging people to not believe everything they hear on TikTok.

“Heat styling damages hair.”

Fact.

High heat can damage the cuticle, weaken the shaft, and make breakage much more likely over time.

This does not mean you need to renounce your blowout and air dry only. It means heat should be treated like something that can cause damage, because it can. Use a protectant and lower the temperature when possible.

My take: Don’t skip the damn heat protectant!

“Frequent trims make hair grow faster.”

Fiction.

Hair grows from the follicle, not from the ends. A trim does not send a motivational speech to your scalp.

What trims do help with is preventing split ends from climbing upward and turning your length into a frayed little tragedy. So no, trims do not make your hair grow faster, but they can help your hair look healthier and retain length better over time.

This is why so many people swear their hair “never grows” when it is in fact growing and then snapping off because they treat their ends like they’re invincible.

My take: trims don’t speed up growth. They just reduce visible consequences.

“Your hair gets used to shampoo, so you need to switch it up.”

Usually fiction.

What usually changes is your routine, your buildup level, your styling habits, the weather, or your scalp. Maybe you added heavy masks. Maybe you’re using more leave in products. Maybe you’ve been abusing dry shampoo. Maybe your scalp is oilier lately. That does not mean your shampoo randomly stopped working because it got bored.

Sometimes what you need is one good clarifying wash, not a dramatic breakup and a new bottle with better branding.

My take: stop cheating on good shampoo because the internet told you your hair has adaptation issues.

“A healthy scalp equals healthy hair.”

Fact.

Your scalp is skin. It holds the follicles, glands, blood supply, and overall environment your hair has to grow through. If it’s inflamed, flaky, irritated, oily, congested, or crusted over with product residue, that matters!

Hair health starts at the root. Literally.

My take: if your scalp is going through it, your hair usually ends up telling on you.

“Hair loss is always genetic.”

Fiction.

Genetics matter. But so do hormones, stress, illness, inflammation, low iron, nutritional issues, medications, traction, postpartum shifts, and general life chaos.

This is part of why so many people miss what’s actually happening. They assume if it doesn’t look dramatic or hereditary, it doesn’t count. Meanwhile, their body is sending extremely obvious signals and they’re trying to solve it with every product under the sun.

My take: not every hair problem is fate. Sometimes it’s feedback.

“Hair transplants are the only real in office treatment.”

Fiction.

Hair transplants get the most attention because they’re dramatic and easy to market, but they’re not the only in office option. Depending on the cause, treatments can include PRP, microneedling, laser based therapies, and other regenerative approaches.

That doesn’t mean every expensive scalp treatment is suddenly genius. A lot of this space is going to get noisier before it gets smarter. But the idea that the only “serious” solution is a transplant is outdated.

My take: hair restoration is expanding fast, which is great for patients!

The bottom line

Hair advice online loves a hard rule because hard rules sell. Never wash your hair every day. Always use rosemary oil. Avoid silicones. Trim it constantly if you want it to grow. Switch shampoos before your hair “gets used to them.” Don’t use heat. Use this serum. Actually, no, use that one.

Real hair care is a lot less dramatic than the internet wants it to be. And also a lot more annoying, because most of the time the answer is: it depends on your scalp, hormones, genetics, stress levels, deficiencies, how you style it, what products you’re using, and whether you’ve been consistent long enough to know what’s actually working.

That may not be as fun as a miracle fix, but it’s usually the difference between genuinely healthy hair and a bathroom full of half used products.

Honestly, I know which camp I’d rather be in.
