thicker hair?

Natalie
Hi! So a few years ago I went through a fit of depression that made some of my hair fall out and my hair has been thinner ever since... I miss my thick strong hair a lot and have teies a few products to help bring it back but nothing has worked too well so far. Is all hope lost? Or are there any products you all would recommend for me? I want it to just thicken back up and be strong like it used to be and I'm really hoping it's not impossible!
