I actually experience the burning when i get my hair done however i have always buy only when i get my roots dyed blonde. If its just foiled and ann all over non bleach color i never have burning and as far as perfume. i had that happen once but happened to be allergic to it so it could be somewhere in the middle for you or totally something beyond my or your knowledge. I would ask ur dr if no one else has a direct answer. Good luck. also if you have your hair dresser put sweetner in the dye mix it helps from burning..
Thanks so much for responding Hopeful23…this is the first time this has ever happened, but it seems any weird thing that goes on, I blame it on GD now…HA!! I never knew the trick about sweetner though…THANKS!!
