At first I wasn’t sure, but when my nails got super thick I knew it was the real deal. Not only that, and I may have to do another review at a later date, but I was diagnosed in 2021 with Androgenic Alopecia. I had thick hair down my back my whole life until my early 40s. My hair began shedding until it was thin and above my shoulders. I have been taking BGVs hair, skin, & nails and collagen also B12, D3, & once a day. My hair is noticeably thicker at the roots and I no longer feel hopeless.Ty!!
