I've dyed my hair MANY times throughout the past few years and never had any problems though I've experienced rashes, redness, and itching from other allergies. Last night I bleached my hair (not for the first time) and I've been sneezing ever since I finished rinsing! I have no skin symptoms, no redness or itching whatsoever, could the sneezing be an allergy to the bleach? Could this progress into a more dangerous allergy if I use that brand again?
