Hairline question

[Peepers]

Hello !
Im 24 years old and ive been noticing my hairline receding a bit in the corners.
Ive been doing research on hair regrowth but i havent seen too many cases as close to mine as i would like for comparison sake, so im not sure if there is something i can do about it which is why im here.

So ill get straight to it. First off im biracial, half black half white. I usually get a bald fade with like a 3 on top when i go to the barbers and have been noticing difference in my line ups. My hairline use to be pretty straight but as i previously stated, i believe the corners may be receding which leaves it looking more rounded now. I will try and provide some pictures so you guys can see what im talking about.

Anyways, my main question is how do i know if regrowing hairs is a legitimate possibility for me?
The parts of my hairline that have receded still have hairs but they are very small, and do not grow longer than like 1cm.(i havent actually measured them lol) These hairs do have color to them though, they are black and i can see them quite easily when i pull my hair back. So they havent completely disappeared which makes me wonder if i have a chance at getting them to grow longer ?

If anyone has some helpful input i would appreciate it
