Is this normal, or am I going bald/thinning

[Shiro]

Greetings guys, my name is shiro.

Recently, well last night actually I tried to photographed my crown area and quite shocked to see that my crown area seems to be thinning or balding. I did had a haircut just a couple weeks ago from a long hair to quite a short hair and I believe the hairdresser did thin my hair a bit. I also style my hair a lot but I always use at least a hair protectant and an Argan oil every few days, while I do notice that my hair falls quite substantially than before this couple of months I feel like, but I don’t really know if the amount is normal or not either, would you guys please give me some thought about it? I’m only 19 this year and it would be quite a bummer to be bald at this age (no offence to anyone though)
Ps: people around always said I have a great thick hair, but I’m still worried about this
Thank you
