The L'Oréal Professionnel Keratin Alpha Sleek range is designed for anyone battling frizz, dullness, or unmanageable texture who wants smoother, shinier hair that lasts. Built around keratin-reinforcing technology, this collection combines a sulphate-free cleanse with intensive smoothing treatments to reshape and protect hair from the inside out.
Begin with the L'Oréal Professionnel Keratin Alpha Sleek Shampoo 300ml, the hero product in this range, which gently cleanses while reinforcing hair keratin without stripping strands. Follow with the Keratin Alpha Sleek Mask 250ml to deeply nourish and smooth, or reach for the Keratin Alpha Sleek Serum 50ml, a heat-activated finishing treatment that seals in shine and blocks humidity. For longer-lasting results, the Keratin Alpha Sleek Progressive Treatment 200ml offers a professional smoothing solution that transforms frizzy hair for up to two months.
Suited to all hair types, particularly frizzy or dull hair craving shine and manageability, this system pairs well with other formulas from the brand. Explore the full L'Oréal Professionnel hair care range for more smoothing and styling essentials.
