Ingredients and instructions for use

Instructions for use
The Smooth Transformer is a progressive smoothing treatment: the more often it is used, the better the results. The effects peak after 4 weeks. Shake well before use. Divide the hair into 2 sections and distribute a palm-sized amount of the product evenly through the lengths and ends. Leave on for 10–15 minutes, then rinse out. Then apply the Keratin Alpha Sleek Serum and, to activate the smoothing technology in both products, blow-dry your hair completely dry and use a straightening iron.
