Prestige hair care sales across Europe grew 24% to €1.2bn in the 12 months ending August 2026, according to exclusive Circana data supplied to Cosmetics Business — the sharpest signal yet that the category's pivot from repair to prevention is paying off.

Serum sales alone rose 101%, and scalp care in the UK has grown 50% over the past five years, per Worldpanel by Numerator. UK scalp treatment sales climbed 12% for the year ending 9 August 2026.

"Hair care has become the new skin care," said Mathilde Lion, Circana's Executive Director of Beauty in Europe.

Hair growth products are the fastest growing sector in hair care, with sales up 32%. Matt Maxwell, Business Unit Director for Health and Beauty at Worldpanel, said: "Consumers are becoming much more aware of hair health and hair thickness, and there is a lot of innovation happening in the hair growth sector."

L'Oréal Paris' Elvive Growth Booster range was the number one health and beauty launch in the UK last year, Maxwell noted.

Why is prevention replacing repair?

Consumers now treat hair and scalp as connected to overall health and wellness rather than as a cosmetic problem to fix.

"Consumers no longer want cosmetic solutions; they want biological solutions that improve the health of their hair from the root," said Lion.

Julia Ramanadhan, President of BondiBoost, sees the parallel with skin care directly: "We saw the move from treatment to prevention – longevity – and it really feels like the same thing is happening in hair care, where people are just generally more conscious about holding on to the hair that they've got."

BondiBoost's Lock Drops Anti-Shedding Scalp and Hair Serum has become the brand's bestselling treatment since launching last summer, and topical scalp treatments are its highest-growth segment.

Hair shedding has become a specific consumer concern, with search interest up 105.6% in Spate data from January 2026 year-on-year.

How are brands formulating for scalp-first care?

Dove's Scalp + Hair Therapy launch — the brand's biggest hair innovation in a decade — shifts from reactive repair to a proactive scalp-first approach. The range includes niacinamide and glycerin to restore the scalp barrier, developed using Dove's proteomics expertise, which maps what hair loses through damage.

Dr. Nichola Conlon, molecular biologist and longevity expert, said: "Hair longevity is really about creating the healthiest possible environment for follicles to function well and hair to remain strong, anchored and growing for longer."

She also warned against marketing overreach: "Longevity can very easily become a buzzword, and I'm quite cautious about 'longevity washing' by putting the word longevity on something without being able to explain the biology or demonstrate a meaningful benefit."

Dr. Catherine Leray, Account Head of R&D at THG Labs, added that brands must make the benefit specific: reduce breakage, improve scalp comfort, support fuller-looking density or maintain hair quality over time.

Cécred, the Beyoncé-owned line, has become Space NK's biggest brand launch in history. Its bestselling product, Edge Drops, is a serum clinically tested to deliver 1.5x visibly denser hair and address signs of shedding.

Where does K-hair care fit in?

Korean hair care, traditionally scalp-first, is expanding into major Western retailers this year, a move expected to continue into 2027. Unove launched in Sephora US and Boots UK, and its new Hydracoat Hair Mist — a milky bi-phase formula with 3HA water and protein milk — claims up to 25 hours of hydration and heat protection to 482°F.

What are the five 2026 trends Cosmetics Business identified?

• Bond repair fatigue: Brands including Olaplex, Briogeo and Oribe are upgrading bond builders from occasional treatments to everyday use, combining structural rebuilding with softness, shine and manageability, per Olaplex CMO Katie Gohman.
• Scalp scalers: K-beauty liquid or gel exfoliants applied pre-shampoo to remove sebum, styling buildup, pollution and dead skin, bringing head spa rituals home.
• Dry shampoo mists: A weightless format designed to refresh hair and scalp without white residue or heaviness.
• Hair longevity: The shift from repair to protection, echoing skin care's evolution from anti-ageing to longevity.
• GLP-1 hair loss: Rising GLP-1 use is driving demand for volumising, thickening and hair loss products, from supplements to four-step routines.

Rita El-Khouri, Senior Vice President of Research and Innovation at K18 Hair, expects the category's definition to keep expanding: "We're still at the beginning of understanding what a truly preventative approach to hair care can look like and I'm excited about this next phase we are in."
