I was losing so much hair the past year, it was downright scary. And my hair which had always been not fine, suddenly became super fine. I even got scared enough I got some of that hair regrowth serum. What a mess. You have to put that stuff on your scalp twice a day. It ruins any hairstyle you have and it leaves your hair dull and sticky at the roots. So I got some hair, skin and nail supplement that had lots of biotin and silicon in it. You should see my hair and nails! After two months it looks like it use to and my nails are gorgeous. (not that anyone sees me or them. lol) If you have thinning hair or nails, I highly recommend a hair skin, and nails supplement. High in biotin. Amazing!
