ur hair looks fine to me however I think in your case a miniturization check by a competent hair transplant doctor will be required, lots of people have small baby hairs at the hairline so its hard to know if its receding so you need to get an idea if miniturization exists beyond the hairline. The side pics are the most telling for me, I see no difference in the before and after photos. U legit have a perfect hairline in my eyes in terms of shape and density so make sure u figure out whether u need finasteride or not.
