That's probably a valid question. All I personally know... I don't have Lyme Disease, BUT I am also super sensitive to smells. BUT I also dye my hair... brown and red. lol The hair dye doesn't seem to bother me, to the point of getting a headache. I cover my nose while it is being applied, and wash my hair right away. It does burn my eyes a bit while being applied, but I also keep them closed.
Funny... I never thought about my "routine," until just now!
