To use Yellow Professional Liss Keratin Smoothing Treatment Kit, begin by washing the hair with the Nutritive Shampoo to prepare it for the straightening process. After washing, rinse the hair and dry it thoroughly. Divide the hair into six sections and shake the bottle of Smoothing Mousse well before use. Starting with the back section at the neck, take sections about half a centimeter deep and apply the mousse using the dispenser, making sure to start one centimeter away from the root. Use a comb to distribute the product evenly through the lengths and ends.

Once the application is finished, let the hair process for 20 minutes. For thick hair that is difficult to straighten, you can cover it with a cap and leave it under a heat source for 20 minutes, then remove the cap and leave it at room temperature for an additional 5 minutes. Do not rinse the hair after the processing time. Instead, blow-dry the hair and then run straighteners over half-centimeter sections, paying close attention to the temperature and the number of passes.

After the straightening is complete, rinse the hair thoroughly and apply the Nutritive Mask. Leave the mask on the hair for five to ten minutes and then rinse it out. Complete the process by drying the hair.
