كيف تجعل علاج الكيراتين يدوم لأشهر

To retain the keratin effect longer, you need to protect your hair from factors that destroy the protective layer, such as usage of sulfate shampoos within the first days after the procedure, sea water, sun, frequent hair washing and hair coloring. Therefore, you should dye your hair and go on vacation prior to keratin straightening.
