The Keratin Hair Growth Booster Capsules are my favorite hair growth support supplements! 😊 I have tried other hair growth supplements with biotin and although they made my hair grow faster, I didn't feel like it improved the quality of my hair. However, the Keratin Hair Growth Booster Capsules are different because they contain biotin AND keratin, which I didn't think would matter, but I've noticed that my hair is looking thicker with less fallout/shedding in addition to growing faster. So, now my hair is improving in both QUALITY + QUANTITY rather than just quantity. Love this supplement and will continue using them 🥰😍
