Allergic!!!

I have used different types of Garnier Fructis shampoo in the past with fairly good results and decided to try the Clean & Fresh - grapefruit as it was advertised as paraben-free. I couldn't figure out the first time why my head itched but after using it a second time, realized it is the shampoo! I've tried to contact L'Oreal in Canada but their phone lines for the Garnier products is down. If you have a remote possibility of sensitivity, do not buy this product!
