Is this hairline too straight and low? If so, how to correct it? (photos)

Maybe a better quality picture and closer would give more details, but from that one I think one side is lower than the other one, I don’t think hairline in general is that low, but I would go a little higher so it could match your face when you get older, we all have certain receding hairline, I would just probably do a little retouch to add density, too symmetric could look fake, so at the end is If what you see there makes you happy

Unfortunately, I see many men with this kind of frontal hairline after hair transplantation. It is obviously not a completely natural looking shape for a mature man. I do not know why many surgeons are doing this as our 2 main jobs in hair transplantation are to make the pattern of the new hairline and make sure that the technicians who place the grafts put less dense grafts in the front and denser grafts in the back to mimic a natural male hairline.In any case, most people will not notice the slight abnormality of the hairline. The only correction could be using laser hair removal to thin out the widow's peak areas a bit.
