normal or balding?

[JSMM]

Hello,

I am and 18 years old guy, turning 19 soon and I've noticed hair loss or it only feels that way to me, that's why I need some opinions from other people to see where I'm at.

I've had long hair since I was like 13 or 14 years old. When I wash it you can barely see any skin on my head through my hair but as soon as it gets a bit greasy (which is very quick) you can easily notice skin. I've been washing my hair almost every day because it gets greasy so quick as mentioned before, or when I do sports it's the same, you can see my head. I'll post some pictures below for you to check it out and see for yourself what I mean.

I've asked my parents and they said that non of their parents were bald they've all had a good set of hair, only when they were getting older the men started losing their hair a little but that's normal I guess, my father is 54 and you can see him starting to bald a bit.

I am worried that I might start losing hair and be bald by the time I am 23 - 25. I would appreciate to hear your guys opinions and I apologize for my bad english my first language is not english.

thank you.
