So my hair has generally been thin i believe. my hairline has not seemed to have receded at all but my scalp is very visible. below are two pics, first from 2014 and the other from 2017, the hair is very dry too and i feel grain like stuff on scalp, very few tho and less now than a year ago. my hair has been similar to this since i was 17, i am 20 now. Thanks so is this me balding? something else? and anything i can try at home like extra iron, more protein ect? my hair is also thing on the back and top.

this one is from 2014 (17 years old)


this one is now (20 year old)

If only it was the just sides, but it's generally thin everywhere, even the front top and back. It's not the noormal receding hairline + thin crown. I feel like what I have to deal with is even worse
