Am I thinning or am I imaginating things?

[This Sucks]

Does not look like much thinning. However, sometime photos can be tricky. They often do not show decreases in volume unless there has been significant hair loss. The cowlick (swirl) in patients with darker hair and lighter skin often tends to look like thinning.

What about a line down the back of the head like this. Does that look like TE or MPB?
