L'Oreal Serie Expert Keratin Alpha Sleek Smooth Transformer

Keratin Alpha Sleek Smooth Transformer is a professional-grade, semi-permanent smoothing treatment mask designed to transform hair with up to two weeks of smoothness, shine, and frizz control. Formulated with Keratin-Alpha Shaper technology and amino-acid chains, this advanced treatment penetrates deep into the hair fiber to smooth and refine the hair at the keratin alpha level for long-lasting salon-quality results. Unlike traditional conditioners or masks that mainly coat the surface, this breakthrough hybrid formula combines intensive hair care with texture-transforming technology to deliver sleeker, softer, and more manageable hair. The treatment helps provide smoother hair, more shine, faster smooth styling, and long-lasting frizz and volume control. Free from alcohol and artificial colorants, it is suitable for all hair types, including color-treated and keratin-treated hair, and is safe to use during color services. *Please note that the formula contains a small amount of cysteine, which may create a technical scent while supporting the product’s smoothing and anti-frizz performance.
