The essential three-product at-home programme for progressive smoothing, created for all hair types seeking longer-lasting control of frizz, humidity and unwanted volume. It combines a gentle sulphate-free cleanse, a weekly professional smoothing treatment and a heat-activated finishing serum.
The programme includes:
• Keratin Alpha Sleek Shampoo — 300ml
• Keratin Alpha Sleek Smooth Transformer — 200ml
• Keratin Alpha Sleek Mirror Sleek Serum — 50ml
Use the Smooth Transformer once weekly after shampooing for four weeks, or every third wash for four applications. Finish each application with the Mirror Sleek Serum before blow-drying and, for optimal results, straightening.
Performance builds from the first use and peaks after four applications. When used as directed, the programme supports up to two weeks of smoother, frizz-controlled hair and faster daily styling. This is a progressive at-home smoothing programme, rather than a permanent or semi-permanent salon treatment.
For conditioning between Smooth Transformer applications, the Complete Routine adds the Keratin Alpha Sleek Hair Mask.
