Once rinsed, dry the hair 70-80%. 2- Application of Keratin: Divide the hair into 4 parts. Apply the keratin in small sections from roots to ends. You don't have to overload your hair with too much product. Once the keratin is applied, we help with a comb to remove the excess product, and we leave an exposure time between 45 and 60 min. observing the absorption of the product in the middle and ends, if it is absorbed, with the excess previously removed, we will give brush strokes where it is needed. 3- Drying and sealing the keratin: remove the excess product again with the help of an extra-fine comb. Dry the hair in sections with a hairdryer and a flat brush. Once 100% of the hair is dry and to cauterize the keratin, pass the iron several times from roots to ends. OBSERVATIONS It should be left between 3 or 4 days before washing the hair again once the keratin has been applied. To maintain the treatment for the maximum time, it should always be washed with a salt and sulfate-free shampoo. Apply special salt and sulfate-free masks.
