My DS thinks his hairline is receding and that overall his hair is falling out. I can't see it myself as he has a thatch of hair you could clean a chimney with, but it is worrying him. It might be Alevel stress. He may or may not be losing it but its not at the stage (if he is) where I could reasonably suggest seeing a doctor. Anyway, leaving aside the reassurance etc that I give him that hes fine, hes not losing his hair and not to worry, are there any practical suggestions that might help that are easy and non medical (if you see what I mean). He has already bought himself rosemary hair oil! Any supplements that aren't too spenny? I've given him Vit D has my nails always grow on holiday but that's as far as we've got. He has a good diet.
