Review (4/5): Great biotin supplement
This form of biotin was suggested by my doctor for general health and to maybe help my thinning hair. My hair now grows a lot faster, and although it hasn't regained its original thickness (probably never will), at least that part hasn't gotten worse. My nails are great. I bought several orders of Elon Matrix 5,000 Biotin, but Escali is the exact same thing and the cost is a lot more manageable. I'm glad Amazon suggested it. Now if the makers could add something to bring back the lush hair I once had, it'd get 5 stars!
