Motions Professional Smooth & Straighten Neutralizing Shampoo with Blue Color Signal.
Directions: Apply a generous amount of shampoo, work up lather and rinse thoroughly with warm water. Repeat at least 2 more times to thoroughly remove chemical residue from hair and scalp - be sure to wash hairline, around the ears, forehead and nape. If lather turns Blue, there is still Relaxer Crème in hair and you must shampoo again. Repeat until lather no longer turns blue.
