This kit contains the following products:
Yellow Professional Liss Keratin Smoothing Treatment Kit is a progressive straightening system designed to smooth the hair fiber, eliminate frizz, and leave hair visibly sleek for up to two to three months. Suitable for all hair types, this professional kit works to reshape the hair structure while helping maintain softness, manageability, and overall hair discipline. It includes a shampoo to prepare the hair, a smoothing mousse that delivers the straightening action, and a mask that helps complete the process by conditioning the hair fiber. So, the straightening is based on glyoxylic acid, a straightening ingredient that helps reshape the hair structure without breaking keratin fibers. Instead of disrupting the internal protein network, this ingredient works by reorganizing the hair fiber to promote a smoother and more aligned appearance.
This system also features the Kera Nutritive Complex, a combination of conditioning ingredients designed to support hair care during the smoothing process. Keratin contributes to reinforcing the hair fiber and improving its overall appearance. Murumuru butter and babassu oil provide nourishing and smoothing properties that help enhance softness and manageability. Aloetrix, an aloe-based complex, helps support hydration and contributes to the overall conditioning performance of the treatment. Last but not least, the mousse texture makes it easier and quicker to apply the product. All in all, this smoothing system helps create sleek hair with a smooth appearance that can last for up to two to three months.
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.
