I am 22 have no family history of male pattern baldness. My brother, my dad, and everybody on my moms side of the family has a full head of fair. When I take a picture in my crown looks thinner then the rest of my hair but it is only visible at a certain angle in bright light. I am assuming it might be because the hair in that area is pointing in a different angle so my scalp is more visible but I am still freaking out it might be because my crown is thinning. Also my temples look like they might be thinning, but I am not sure if they were always like that or my hairline is maturing
