Is this the start of going bald?

[CR4YF1SH]

Hello all,

I am 22 and have always had quite thin hair AND a widow's peak, meaning it is hard to tell if my hair is thinning or not. However recently I have started becoming more conscious of this spot on the back of my head. This could just be a cow-lick but I am unsure. I have tried to take photos of it in all different kinds of light (flash, no flash, overhead and natural) so that others might be able to tell me what they think. I asked my girlfriend but she just said it looked the same. I think it is hard to tell if something has changed or properly looks like if you see them everyday; which is why it is quite hard for me to say. I hope that someone might be able to help. I have already started used Alpecin as a precaution, but want to know if I should go any further.

Regards,

C
