I have never written a review on any product I've ever bought online. That being said, this product is so amazing, I had to. I was losing my hair mid-shaft (basically had an unwanted mullet) for a year and a half, I stopped dying my hair, I see my hairdresser every 8 weeks, he hadn't cut my hair in over a year, because there wasn't much to cut. I was taking a bunch of other supplements hoping that would help, I tried castor oil, rosemary oil, and scalp massages, to no avail. I am in Perimenopause, my doctor told me it was normal for my age. I had a physical coming up and my doctor was out sick so I saw her PA, she was incredible, she tested my Ferratin, it was a 14! she said although that's technically in the "normal" range, she said women should ideally be 75 or higher. She prescribed me and iron supplement. I took it but did some research on my own. This product kept popping up, and the ingredients matched what my research was saying about the absorption of iron being much better when combined with other vitamins. In two months, my Ferratin more than doubled to 37! My hair almost back to where it has always been. I went to the hairdresser and he said " wow! I can actually cut and blow out your hair"! I am a customer for life now!! Thank you!!!
