Skincare went scientific, now hair care is following. Shoppers now buy serums and scalp treatments, and read the ingredient list before they buy. At the same time, some of the category's oldest products are being judged in court. This report brings you up to speed on the whole hair care market.
12 sections to help founders and investors understand the hair care market with clarity
Hair care gets mixed up with salons, hair-loss clinics and hair dryers, so we begin by saying what counts and what doesn't.
A shampoo, a bond-repair mask, a scalp serum or a box of hair color is in. So is a styling cream sold to salons. A hair transplant, a prescription hair-loss pill and a flat iron are out.
This way, the market size and every brand we compare refer to the same products.
Hair care is one of the fastest-growing parts of beauty, but the safety of some of its products is now being decided in court.
We've found a lot of interesting signals. For example, Circana reported in August 2026 that US prestige hair care sales grew 11% in the first half of the year, with hair serums up nearly 60%. And in September 2026, Arizona sued L'Oréal, saying it sold hair relaxers like Dark and Lovely without warning about cancer risks, while more than 12,000 similar claims wait in federal court. Shoppers are paying more for hair treatments, and they expect the products to be safe.
In this section, we look at why people now treat their hair like their skin, which products are driving the growth, and what the relaxer lawsuits could mean for every brand selling to textured hair.
Hair care numbers online often add in hair dryers, salon services or prescription hair-loss drugs, so they're hard to compare.
We build our own estimate, starting from what brands actually sell. Then we compare it with outside sources and explain every assumption, so you can see where our number comes from.
We also show how the number moves in a cautious and an optimistic scenario, for example if mass shoppers keep cutting back while prestige buyers keep paying more.
Damage, frizz, thinning, an itchy scalp: almost everyone has a hair problem, and most have tried several products that didn't fix it.
We compare six kinds of hair care companies, from supermarket shampoo brands to salon brands, textured hair specialists and scalp and thinning care. Then we rank what their buyers need most, like products that match their hair type, proof that a treatment really works, and ingredients they feel safe using.
This shows which hair problems people will pay more to solve, and which ones they'll keep handling with a cheap shampoo.
Hair care used to be about washing and styling. Now brands sell repair, scalp health and longer, thicker hair, and they need the science to back it up.
We go through what sits behind today's products: bond-building and repair ingredients, peptides for thinning hair, scalp serums, safer straightening and color formulas, and the tools that diagnose hair type or mix custom shampoo. We also show where things get stuck, like claims that are hard to prove, ingredients under legal pressure, and formulas that work on one hair type but not another.
You'll see which new ingredients and tools already change what people buy, and which are still mostly a story on the label.
Supermarket and pharmacy sales, beauty retailers, salons, a brand's own website, subscriptions and custom formulas: hair care companies make money in different ways.
We compare who pays and where the margin goes. Mass brands sell huge volumes at low prices and fight for shelf space. Salon brands earn trust through stylists, but share the margin with the salon. Prestige treatments sell for much more per bottle, though marketing costs are high. Subscriptions and custom formulas keep customers longer, but only if people reorder.
You'll see which models hold up when mass shoppers cut back, and which ones depend on a single product staying in fashion.
Some brakes are easy to see: crowded shelves, mass shoppers who trade down, and cheaper copies of every product that works.
Others are easier to miss. Lawsuits over relaxers and straighteners could reach other products. Rules on ingredients keep changing from one country to the next. Salons are under pressure, so they sell less. And claims about hair growth are easy to make and hard to prove.
We go through these risks one by one, rate how likely each is, and explain which brands would be hit hardest.
Hair care is growing for reasons that go beyond the next viral styling trend, so we lay them out one by one.
Some drivers are easy to see: people paying more for treatments, more interest in scalp health, and an aging population worried about thinning hair. Others feed each other. Once shoppers buy a serum, they add a mask and a scalp product. Stylists who see results recommend the brand to clients. And brands made for textured hair keep finding customers the big players served badly for years.
Before building or investing, you should know what turns a one-off hair purchase into a routine, and what makes shoppers trust a brand with their scalp.
Investors like hair care because people buy it again and again. But they want brands with repeat buyers, not one viral mask.
We compare recent rounds and deals across hair treatments, scalp and thinning care, textured hair brands and salon brands. We also look at whether big groups prefer brands that grew in salons or online, and which newer bets, like custom formulas and peptide serums, are getting funded.
You'll see which hair care brands investors are backing right now, and what a younger brand needs to show, in reorders and margins, before it can raise.
K18 and Moroccanoil are the names people know from salons and social media, but they're only a small part of the hair care market.
Many interesting brands stay out of the spotlight. Some only make products for curly or coily hair. Others focus on thinning hair without a prescription, sell mainly through stylists, or develop the ingredients that bigger brands put in their bottles.
They're hard to compare because hair results are personal: a product that works on fine hair can fail on thick curls. Many brands sell mostly in salons or abroad, and most are private, so their real sales stay hidden.
Below, you'll find the market grids and ecosystem maps we've built to show who makes what, who sells where, and where newer brands are finding room.
A great first wash is easy. Getting people to reorder after the third bottle is the hard part.
So we studied why hair care startups fail or stall. Some promised thicker hair and couldn't prove it. Others grew through salons, then lost them when they moved into supermarkets. And some depended on one hero product that bigger brands copied at a lower price.
If you're building, you'll see why proven results, a clear sales channel and reorders matter more than a viral launch. If you're investing, you'll know what to check about claims, channel conflicts and how much rides on one product.
Mielle, Color Wow, Prose… a few hair care brands found a clear problem to solve and built a real business around it.
Mielle started with products for textured hair, grew a loyal following online, and was bought by Procter & Gamble. Color Wow built best sellers around frizz and dry hair, then agreed to sell to L'Oréal. Prose mixes custom formulas for each customer and sells them by subscription, a model that still has to prove it can grow as big. Each path is different.
We'll look at how these teams chose one hair problem, won customers who came back, and decided when to grow alone or sell.
It's for founders, investors, beauty groups, salon owners, retailers, ingredient suppliers and strategists who want a clear view of hair care.
