I guess I'm balding :(

[Wakkoz]

Hey guys!
I turned 19 in january and since then I felt something strange with my hair. It just started to look thinner to me but I stopped paying attentions n for a while.. until I decided to take some photos today and from what I saw, I guess I am going bald. My grandpa on my mom's side is the only bald relative I have but everyone says I have the same hair that he had , so I guess I'm doomed . Anyways, I'll post the pictures in case someone could recommend any steps I can take to prevent the hair loss or maybe slow it down? Thanks guys and have a great day!
