KERATIN HAIR MASK is a hair care product developed to help achieve brighter, livelier and straighter hair. It aims to create a softer hair structure by supporting the natural moisture balance of the hair and helping damaged hair regain its former naturalness. Keratin hair care mask, which helps eliminate the keratin deficiency in the hair, aims to straighten the hair with regular use. HOW TO USE? We recommend that you apply the keratin hair care mask at least 30 minutes before showering. Apply a sufficient amount of the mask according to the length of the hair, massaging it from the roots to the ends. We recommend using a straightener after rinsing after application. For effective results, we recommend that you apply Keratin hair care mask regularly, twice a week. It was developed by PROCSIN Türkiye.
