Four full-size products create a complete cleansing, treatment, conditioning and finishing system. With consistent use, the routine progressively improves smoothness and frizz control, helps reduce unwanted volume, and leaves hair softer and shinier. The Mirror Sleek Serum adds humidity defence and heat protection up to 230°C. Suitable for all hair types.

The complete four-product at-home smoothing programme for hair prone to persistent frizz, humidity and unwanted volume. Designed for all hair types, it combines weekly progressive smoothing with nourishing care and a heat-activated finish for softer, smoother and more controlled hair.
The routine includes:
• Keratin Alpha Sleek Shampoo — 300ml
• Keratin Alpha Sleek Smooth Transformer — 200ml
• Keratin Alpha Sleek Hair Mask — 250ml
• Keratin Alpha Sleek Mirror Sleek Serum — 50ml
Use the Smooth Transformer once weekly after shampooing. On other wash days, use the Hair Mask instead; the two treatments are alternated, not layered. Finish every routine with the Mirror Sleek Serum before blow-drying and, for longer-lasting results, straightening.
Performance builds through consistent use and peaks after four applications. Used as directed, the complete routine supports up to two weeks of frizz control. This is a progressive at-home smoothing programme, rather than a permanent or semi-permanent salon treatment.
