The hair is up to 85% keratin, which forms both the interior structure and the outermost layer. The loss of keratin due to heat styling or chemical treatments makes your hair dry and prone to tangles and frizz. BLONDWOOD keratin mask allows to replenish missing keratin in just 5 minutes, and dramatically improve the condition of your hair. To minimize the unwelcome changes in your hair due to keratin loss, we recommend applying BLONDWOOD Keratin mask 1-2 times a week. Keep it from 5 to 10 minutes depending on your hair condition and desired result. If you have blond hair, we also advise trying our Purple mask to get rid of yellow and brassy hues and get a brighter color. Apply to hair after shampooing, ensure complete coverage from roots to ends. Leave on hair from 5 to 10 minutes. We highly recommend relaxing while waiting for treatment to act. Have some YOU-time, relish the pleasant aroma of our mask, and let your hair enjoy the renovation process. Then rinse off with warm water. We know that you want to get ideal hair in just 10 minutes.
