Harsh lighting? Diffuse thinning? What is going on..

looks like thinning in some pictures. No thinning in others.

If you want a definite answer i'd seek advice from a doc/derm/hair specialist.

Hair density differs from person to person. So if this definitely HAS always been like this since you were a child, I guess it's normal.

But if you want to stop MPB, then you need to make sure it IS MPB and try sorting it.

Your double crown looks perfect in one or two pictures. But thin in others. Strange. Again, lighting/density issue. You need to get it checked to be certain.

Yes in some pictures it does look normal, but when I'm really in strong sunlight or camera flash then it really looks bad. This is what freaks me out, it looks normal under normal light, just bad with really strong light. Also the pics I had just woken up so my hair was a little messy.
