I have naturally curly hair that I am having the hardest time finding a shampoo for. I am allergic to sodium sulfates, so if anyone knows a good shampoo that uses ammonium I would appreciate the recommendation.

I have hair thats pretty oily at the roots but dry at the ends as is customary with curly hair.

There is a website entirely devoted to curly hair www.naturallycurly.com.

HTH! :)

I'm not sure about the ingredients, but it might be worth taking a look at Nexxus Therappe shampoo and Humectress conditioner. They aren't formulated specifically for curly hair, but they work wonders on mine.
