Telogen Effulium? Looks A Bit Suspicious

[Alpha Tortoise]

15YO Don't really know whether I'm experiencing male pattern baldness symptoms but my right side of my hair is looking a little thinner then the left or atleast it seems that way since i have finer thin hair and i part it too the other side,
