Hairline Thinning Out Fast But Is This Maturing Or Should I Get On finasteride? 21 Years Old

[recedingornot87]

So as the title says my hairline is thinning out very quickly. My dad was a NW6-7 at 21 years old and ive been a NW1 up until a few months ago when my hair started rapidly receding and thinning. Does this look like it could be a maturing hairline or is it worth getting on finasteride? Currently ive been using minoxidil on it to hopefully slow down or to make it thicker but so far its only gotten worse since I started taking it in december.
