For salons across the UK, keratin smoothing treatments remain one of the most in-demand and profitable in-salon services. Clients want smoother, frizz-free hair with long-lasting shine — and stylists need treatments that deliver consistent results efficiently.
Introducing KCRIO™ Restorative Keratin System from Keratin Complex — a next-generation, formaldehyde-free keratin smoothing treatment designed for modern salon environments and real-life hair.
Built to perform in humidity, reduce frizz, and restore hair from within, KCRIO delivers sleek, glass-like results that last up to three months — while supporting salon growth and efficiency.
