16 And Thinning Or Just Paranoid???

[Johan guiterrez]

have seen this on the back of my head, but I've never seen it this big before..... all pictures with dry hair and flash in a semi dark room. hairline is normal because looks like my moms, but this got me nervous. also I've noticed hair falls out a lot more on the top of my head than it used to sometimes from the back never from the sides. hairs always greasy and really itchy but idk if that has anything to do with it lol

I think it only is the parting of the hair.
For peace of mind, take same pictures with same light and same hair length... one year from now, then compare.
