Quick Answer
Korean hair care is a real US retail trend in 2026, and the opening for a US brand is the hair strand, not hair loss. Ulta and Sephora both added Korean hair care brands this year, and NielsenIQ names hair care a fast-growing K-beauty category. Shine, smoothing and damage-care claims stay cosmetic in the US. Hair-growth, hair-loss and dandruff claims make the product a drug.
Key Takeaways
- Ulta and Sephora both added Korean hair care brands in 2026, and NielsenIQ calls hair care a fast-growing K-beauty category.
- The new lineup reaches past the scalp to the strand: essences, mists, oils and shine treatments.
- Claims about how hair looks and feels stay cosmetic. Hair growth, hair loss and dandruff claims make it a drug.
- A Korean functional cosmetic claim for hair loss symptoms cannot move onto a US label.
- Brief your Korean ODM on format, fragrance, silicones, packaging and US claim wording before the first sample.
Until recently, the Korean products that won US shelf space were mostly skincare. In 2026 the hair aisle caught up.
This guide covers what US retailers added, how scalp care and hair-fiber care compare, and which hair claims stay cosmetic. It ends with what to settle with a Korean ODM before you sample.
What Changed for Korean Hair Care in US Retail This Year?
Ulta and Sephora both added Korean hair care as a category of its own in 2026. Ulta added an inaugural 13 Korean hair care brands in March, as WWD reported on Ulta's Korean hair care launch. About half sell only through its online marketplace, and six were slated to enter more than 600 stores in April.
At Sephora, Unove arrived in mid-January as the retailer's first Korean hair care brand, per Glossy's report on Sephora's K-beauty hair care push, and Dr. Groot's Sephora launch announcement set Sephora.com for April 1 and stores from May 15. Glossy also reported that Dr. Groot was one of several Korean hair care brands Sephora planned to add this year.
The sales data points the same way. NielsenIQ's 2026 K-beauty report says facial skincare still leads, while hair care emerges as a fast-growing category.

Scalp Care vs Hair-Fiber Care: How the Two Compare
Scalp care and hair-fiber care solve different problems, and that difference decides your claims. Scalp care refers to products that treat the scalp like facial skin. Hair-fiber care is care for the strand itself: shine, smoothness, frizz and damage.
Scalp care came first. Dr. Groot, the best-known Korean hair brand in the US per WWD, built its name on scalp care, and the idea behind it is explained in the scalp skinification trend piece.
The 2026 retail lineup reaches further down the strand. WWD lists Narka's hair essences and hydrating mists in Ulta's in-store group, next to Lilyeve's scalp serums. Glossy describes Unove's range as frizz control, "glass hair" shine and damage care, with a hair mask, a leave-in conditioner and a hair oil.
| Scalp care | Hair-fiber care | |
|---|---|---|
| What it works on | The skin of the scalp | The hair strand, from root to tip |
| Typical Korean formats | Scalp serums with brush applicators, scalp scrubs, treatment shampoos | Hair essences, oils, hydrating mists, masks and leave-in conditioners |
| US claims that stay cosmetic | Cleanses oil and buildup, leaves the scalp feeling fresh | Adds shine, smooths the look of frizz, softens and detangles |
| US claims that make it a drug | Stops hair loss, regrows hair, treats dandruff | The same claims, if a strand product makes them |
| Main risk for a US launch | Korean hair-loss wording copied onto the US label | Fewer claim risks; the contest is texture, scent and packaging |
Most of the claim risk sits in the scalp column. The strand column is where a first-time brand can compete on texture, scent and packaging without drifting into drug territory.
"I'm Liz, I run altameet from Manhattan, NYC. With Korean hair care, read the claims on the Korean box before you fall for the formula, because those are the words that cannot travel. If you want a quick gut-check on whether Korean ODM fits your project, I'll give you 15 minutes free."
Which Hair Claims Stay Cosmetic on a US Label?
Claims about how hair looks, feels and smells stay cosmetic in the US. FDA decides by intended use, and its own examples of drug claims include products that will restore hair growth, as its cosmetic or drug guidance explains.
Hair-growth and hair-loss-prevention claims fall under 21 CFR 310.527, which treats any such OTC product as a new drug that needs an approved application. Dandruff claims follow the OTC dandruff monograph, and the zinc pyrithione shampoo guide walks through what that takes.
Korea draws the line in a different place. A functional cosmetic is a Korean regulatory category for cosmetics whose benefit is reviewed by or reported to MFDS, and helping relieve hair loss symptoms is one of those benefits. That status does not exist in the US, so the claim cannot travel to a US label even when the formula stays the same.
Cosmetic wording to work from:
- Adds shine and a glossy, glass-hair look
- Smooths the look of frizz and flyaways
- Softens, detangles and makes hair easier to brush
- Fuller-looking or thicker-looking hair
- Cleanses oil and buildup from the scalp
Wording to keep off a cosmetic label:
- Regrows hair or stimulates growth
- Stops, prevents or reduces hair loss
- Treats dandruff or an itchy, flaking scalp
- Strengthens follicles or roots
Watch the word fall. Some export copy says hair fall for hair loss, and a US shopper reads it the same way.
Online First: How Retailers Are Testing Korean Hair Care
Both retailers started much of their Korean hair care online before giving it shelf space. Ulta's vice president of hair care merchandising called its online marketplace "a great testing ground," per WWD. Products sold there are fulfilled by the brand rather than by Ulta.
For a new brand, that changes the plan. An online-first retail launch means you hold the inventory and ship the orders yourself, which is closer to direct-to-consumer than to a classic wholesale order. The playbook for selling Korean cosmetics in the US covers the channel choices.
Packaging is part of the pitch. In WWD's report, Ulta's vendor partner pointed to Narka's jelly dry shampoo wands and Lilyeve's bristle-brush serum applicators as packaging innovation. A container is a decision, not an afterthought.
Which Korean Hair Products Fit a First US Launch?
Strand products with appearance claims are the simplest first launch. A hair essence, a leave-in mist, a hair oil or a rinse-off mask can be sold on shine, softness and frizz alone.
| Product type | US status with cosmetic claims | Watch-out |
|---|---|---|
| Hair essence or oil | Cosmetic | The silicone choice changes slip, shine and the shelf claim |
| Leave-in mist | Cosmetic | Spray pump fit and preservation for a water-based formula |
| Rinse-off mask or treatment | Cosmetic | Texture and rinse feel are what shoppers judge |
| Scalp serum | Cosmetic if the claims stay on cleansing and feel | Any hair-loss wording turns it into a drug |
| Hair-loss or dandruff shampoo | A drug in the US | Not a cosmetic launch; see the claims section above |
Scalp products still work if the label stays on cleansing and feel. The Korean scalp care private label guide covers how to build that line.
Five Decisions to Brief Your Korean ODM
Settle five things in the brief before the first sample: format, fragrance, silicones, packaging and the US claim wording. Each one changes the formula or the label, and changing them after sampling costs you a round.
- Format: essence, oil, mist, mask or shampoo, and leave-in or rinse-off.
- Fragrance: how strong, or fragrance-free, plus the fragrance supplier's allergen list.
- Silicones: with or without, since that changes slip and shine and decides whether you can say silicone-free.
- Container: pump, spray, dropper or applicator, and whether the ODM fills that format in-house.
- US claims: the exact front-label phrases, written in cosmetic language before any claim testing.
Hand the ODM the US wording, not the Korean box copy. A Korean product page that leads with a functional claim will carry it straight into a direct translation.
Korean hair care is reaching US stores through the same retailers that carried Korean skincare. The products that travel cleanly keep their claims on shine, smoothness and feel.

Frequently Asked Questions
Can I sell a Korean hair-loss shampoo in the US as a cosmetic?
Only after the hair-loss claims come off. The same cleansing formula can be sold with cleansing and appearance claims, but a promise to stop or reduce hair loss makes it a drug under FDA's intended-use rule.
Is "thicker-looking hair" a cosmetic claim?
Yes, when it describes appearance. Thicker-looking and fuller-looking describe how hair looks. Claims that hair grows thicker or that follicles change describe the body and read as drug claims.
What is glass hair?
Glass hair is a K-beauty term for very glossy, smooth hair that reflects light like glass. Products sold for that look are shine and smoothing products, so their claims usually stay in cosmetic territory.
Does a Korean functional cosmetic approval count in the US?
No. It is a Korean status for the Korean market. A US label follows US rules, so a hair-loss benefit approved in Korea has to be dropped from a US cosmetic or sold through the US drug route.
