Ok so I have pale skin (does not tan, burns), blue/greyish eyes. My natural hair is medium brown. For years I loved the dark hair

and dyed it red at times. My hair is showing grey too. Recently I have thought about going blonde but I do not have the balls to go for it because if it looks shit its going to be a pain in the ass to change backor grow out. I also hate it when blonde hair is showing dark roots so thats probably what will happen to me.
anyway, how to tell if you suit blonde?
