Hmmm. In my early twenties, my hair started shedding a lot (I was experimenting with vegetarianism, and probably had a nutrient-deficient diet; but what did I know, back then I was an idiot leftist, too...) and is now quite thin.

Do you think supplementation would help?

At 19 I lost a lot of weight and mine thinned a bit (I still have enough for three people). Eating better won't hurt at all, but it may take time before any improvement shows up. If not, I don't know what to tell you.
