Which dry shampoo is free of harmful ingredients?

A “clean dry shampoo” is a product that avoids ingredients that can weigh the hair down or irritate the scalp. This includes sulfates (which can be drying) or heavy silicones (which can leave residue). Look for formulas with gentle, absorbent ingredients such as rice starch, corn starch, or clay, and possibly caring additives like provitamin B5 or aloe vera extracts.

Clean Slate is a good example, as it has a mild formula without drying alcohols and uses absorbent ingredients to keep the hair fresh without leaving heavy residue.
