MK Biotin Therapy is the first natural liquid biotin (B7) formula that is introduced directly into the hair shaft. Our research teams were able to convert biotin, also known as vitamin “B7”, into very small molecules that can be easily absorbed into hair follicles during treatment. Biotin “B7” is crucial for the health and strength of your hair. This formula is also enriched with natural proteins, keratin amino acids and collagen to eliminate frizz, reduce volume, smooth, soften and deeply repair hair. It’s a great new formula for healthy, natural looking and strong hair.
