Centrum Silver helps. Also biotin and selenium supplements. If it is significant enough you want to try there are shampoos that can help. I used Nioxin but my stylist said that it no longer contains the active ingredient (DHT) that it had back then. She said it wasn't as good but it still gets good reviews. There are other DHT shampoos out there. It made a huge difference for me (my hair came out on depakote then I had lithium toxicity for months before we caught a high level thanks to vomiting all the time and that screwed up my thyroid so the combination of 3 was leaving me receding patches along my scalp line). Then when it was growing back in I started menopause and had a gyn procedure and that caused me to start to lose hair again and that time the vitamins fixed it. I'm well into menopause and post-hysterectomy now and my hair is different but not falling out anymore (I'm also off lithium and have no idea what effect that's having).
