What is it?
Ammonium thioglycolate is a reducing agent in alkaline permanent hair wave solutions.

How can I avoid it?
This substance rarely causes allergic reactions, but when it does, it must be avoided. It is more likely to cause irritation, so gloves should be worn when handling alkaline cold permanent wave solutions. These substances may also cause irritant contact dermatitis. By law, all products made in the U.S. for topical use have the ingredients listed either on the product package or the box 
that contains it, so check the labeling of your skin or hair care products for this ingredient. If there is not enough information, ask your retailer or contact the company directly. At work, request a Safety Data Sheet (SDS) to help identify potential sources of exposure.
