I have a neighbor who itches whenever her shampoo or body wash hits her legs. I believe it could very well be an issue with the sulfates.

She didn't itch from the salon sulfate-free shampoos I gave her small samples of to try, but they're too pricey for her income.

Are there any cheap non-sulfate shampoos that are GENTLE?

I guess natural or organic are OK to list too, if some can be found in regular grocery stores & are fairly inexpensive.

Though I think I remember Avalon & Aubrey Organics leaving my hair feeling matted & stripped. Yet her hair might react differently to them.
