My hair is completely like a scouring pad.

All that thick hair I used to have is gone. T_T At least my hair was on the thicker side, so it used to be healthy. But as I get older, it's gradually thinning and losing all its nutrients. Since I have so little hair, I can't even dream of getting a straightening treatment, so I get a perm instead. Because my hair is fine and lacks nutrients, it really feels just like a scouring pad. No matter how many treatments I get at the salon, it doesn't help. Nothing I apply works. T_T What am I supposed to do with this scouring pad? T_T
