Query: Allergy sufferers beware!

Dove has traditionally been known for gentle products, but this shampoo caused major allergy problems for both myself and my daughter. This shampoo has a VERY strong odor, which caused intense nasal congestion for both of us within seconds after applying the shampoo. Furthermore, my daughter's cheeks became red and swollen about an hour after using the shampoo. She was still sneezing 2 hours after using the shampoo, and she finally felt better after we washed her hair (with another shampoo) and gave her Benadryl. My daughter's 11, and this is the first time she's ever had an allergic reaction to a fragrance. The smell also gives me a headache, so I have to keep my distance from other family members who use it.That said, not everyone in my family has problems with the smell (which is otherwise pleasant). However, I would be wary of purchasing this product if you are sensitive to strong fragrances or have sensitive skin.
