I dont know what is the main reason of these changes, if its density or what?
if its because of Telogen Effluvium or AGA or something else?
Hair color change isn’t usually linked to TE or AGA. Shedding could be TE if it’s diffuse, but color shifts might be unrelated. Check for other factors like age or nutrition. For more info on TE and AGA, check The Beginner’s Guide.
