Read the reviews on this product and decided to try it, as I had been losing a lot of hair for several months. I’ve had an underactive thyroid for twenty years. I am 65, the hair thinning was distressing. I am pleased to say this product has definitely improved the condition of my hair over the eight or so months I have been taking it and the shredding is markedly decreased. I would recommend this product. I am now taking one tablet a day to maintain this result
