Does hair dye contribute to hairloss?

[River]

Hey guys,

I first noticed I was losing hair about 3 years ago, when I was 25, and I found that by dying my hair black, I was able to camouflage it quite well. I still dye my hair, but I have noticed a progression from norwood 2 to the early stages of a norwood 3.

I began taking finasteride 30 days ago, and while researching studies of the efficacy of this drug, I found that study participants were not allowed to dye their hair whilst they were on finasteride.

This has made me wonder if hair dye has contirubted to the progression of my hairloss. Does anyone know if there any evidence out there that dying your hair can make MPB related hairloss worse?
