Diffuse thinning or telogen effluvium?

[Contradictedsoul]

How do you tell the difference?

Does diffuse thinning mean diffuse pattern alopecia?

How do you tell the difference between DPA/Diffuse Thinning and Telogen Effluvium?

I suspect I have telogen effluvium due to not only joining a wrestling team and going through training that helped me lose more than 20 pounds but I did it without any proper diet as well, which is why I feel like my hair loss is telogen effluvium. Although after seeing pictures of DPA and Telogen effluvium, they look the same. So how do you differentiate?
