Hi! I just discovered this site and hope I can contribute helpfully to others! I have been using Rogaine (5%) since my hair began to thin when I was 16 and I was diagnosed with PCOS. My hair never went began to being extremely thick, but I was always satisfied that it kept it at a pretty normal thickness. I am now 25 and 5 months pregnant. I haven't been using the ROgaine, as I've been told it can be harmful for the baby, and my hair has gone back to extreme thinness. I was wondering if anyone knows of any other treatments that I can use at least for the rest of the pregnancy that might restore it a bit, without the danger? (I heard maybe Revivogen is an option? Is it safe and is it effective? Anything else?) I will of course run any suggestions by my doctor before going out and buying, but I figure you guys might know about more products offhand than he does, and then I can confirm safety with him. Thanks!
