ITA. Well said. There are things that I can't use AT ALL. It doesn't mean that they're not good products, it's just that "I" tend to have allergic reactions to them.
I can understand the product makers being concerned about their reputation (folks tend to RUN when they hear anything that can be perceived as negative), however if I were making products, I'd definitely want to know if someone had a reaction so I could come up with a better non irritating formula or issue a disclaimer.
EDTA: Yes I've had some reactions. Cantu Shea Butter whatever that crap is messed me up pretty bad. Migraines, itching, and my skin was sore to the touch from my scalp to my face and neck. V05 Moisture Milk (strawberries & cream) left me with chemical burns.
