Customer Review: "The quality of the Hair Strong Gummies are the best I have seen in a while. Usually when taking vitamins with Biotin it causes acne and leave spots on my face from hyperpigmentation. However, the heart shaped yummy gummies have been the best I have tried. My hair sheds less, is much stronger, and I know longer apply acrylics to my nails because the because they grow beautifully. I will definitely continue with this in my selection."

Customer Review: "I was hopeful, but skeptical going in to trying these, as I think many are, and I had a few "tests” in mind for me to identify what, if any results I’d achieve with these supplements. First, no noticeable adverse reactions (I have food allergies and sensitivities, and luckily no issue with these for me). I also took a before photo and a photo again after six weeks of use, and really noticed a significant improvement in lifting and tightening of sagging jowls, my existing lines and wrinkles are significantly softer, my skin looks more plump, and my skin tone is more even, as I started with melasma. The second test was, 'Will anyone else notice if I don’t say anything?' My husband, my mom, and my closest friends all asked me what I’ve been using after four weeks because they already saw a huge difference and they all wanted to try too!"
