The announced end of formaldehyde in Europe
Since 2025, European regulations have been tightening the thresholds of free formaldehyde allowed in professional hair products (< 0.2%). In 2026, several countries are moving to a total ban in salons. Salons are anticipating this by switching to formulas based on glyoxylic acid or vegetable tannin.
The rise of tannin
Vegetable tannin smoothing (bark extracts, black tea) is attracting an eco-conscious clientele. The result is more natural, lasts 3 to 4 months, and the protocol is free of toxic fumes. ULTRALISS brands already offer complete ranges (Prime Bio Tanix).
Korean straightening takes hold
Popularized by K-Beauty, Korean straightening relies on a keratin + vegetable oil cocktail without formaldehyde. It aims for the glass hair, a spectacular mirror effect. JANNA COSMETICS distributes one of the only certified European professional formulas.
AI-assisted diagnostics
New for 2026: AI-powered photo diagnostic tools analyze hair porosity, elasticity, and chemical history in 30 seconds. Some ULTRALISS pilot salons are testing integration into the customer journey (product recommendation, personalized protocol).
The eco-conscious client
The demand for traceability, recycled packaging, and clean formulas is exploding. Salons that display strong certifications and transparency are attracting a premium clientele willing to pay +25% vs. standard service.
