I love this product, it is GREAT! I have been trying different biotin products since my dermatologist recommended it because my hair has gotten thinner and I think I will be sticking to this one for a while. The quality of the ingredients is very good, the caplets are very easy to swallow and after using it for a couple of weeks I can tell this product is a little more effective than others I have tried before because I can notice a slight improvement on my nails (they break soo easily). One of the best value products I’ve found since there are 90 units per container and you only have to take one a day (10,000) so it is super convenient not having to re-order that often)... and they have Prime 2-day delivery!!! what else can I ask for?!?!
I only started taking this product because my hair stylist insisted it would help my hair grow out. I started growing my hair out around August 2017, and have only gone for regular trims every 3-4 months. I started with it a little past chin length. The first photo was the progress in early October 2018, the second is the end of January 2019, and the last one was the other day, early May 2019. My hair has always grown so slow despite taking good care of my hair, following a well balanced diet, and exercising regularly. I started taking this supplement right after the second picture was taken. I’m amazed by how much my hair has grown in 3-4 months! It definitely grew more between end of Jan-beginning of May, than it did between early October and end of January. I even noticed more eyebrow growth too, which I was not expecting. Definitely would recommend at least giving it a try! I had zero expectations, and was planning to discontinue the supplement after the first bottle, just so I could tell my stylist I had tried it. I just ordered my second bottle!
