I have noticed over the last year thst staring in May or June I start shedding like a cat. I do color my hair (only roots) every six weeks, but once the cold weather comes, it slows down and my hair starts to grow again. I am taking multi vitamins, with biotin and all the other vitamins for hair, but it does not seem to work. I am healthy, aside from arthritis, not on any meds, work out 7 days a week, and am about 122. I eat well, not alot of fat, and little to no stress, no kids. arghhhhhhhhhhhhhhh! I always had beautiful hair, now at 43, it is starting to act older than I am. Is anyone else shedding seasonally like me??????
