18 Years Old Balding

[samskeyti]

Hello Everyone.
As it's written in the title I'm an 18 years old male and I'm very confused about whether I'm balding or not.It's been 14 months since I haven't had my haircut.Approximately 6 or 7 months ago I noticed a thinning on the crown area of my hair.I worried a lot about it but did nothing to learn what it was.I've been monitoring it since I noticed and it seems like it hasn't progressed and even it has,it's not possible to realize it.
