Am I Balding?

I am 23 years old and there is no history of balding in my family.

Your hairline is very low in the mid-line so I would expect that the middle would eventually move up about 3/8th of an inch.  This would change what the corner looks like.  You could have an early Class 3 balding pattern, but I recommend you get a HAIRCHECK test to see if there is balding present that you can’t see.
