Unsure Thinning

[Artista]

Understood Not Me..those types of issues you brought up are generally temporary my young brother-Keep your constitution STRONG-no worries.
One more thing, You are very young,,IF you do suffer from some degree of hair loss, there WILL be viable hair loss treatment(s) available to you in the relatively near future.

It's hard to tell if you're definitely thinning or not because natural, pre-balding density can vary and we can't tell if your hair has changed. You may be in the very early stages of hair loss.

Bottom line is: You still have a great head of hair. You've spotted it early and by acting fast and getting on the treatments it's very possible to prevent it from progressing.
