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 CrÃ¨me in hair and you must shampoo again. Repeat until lather no longer turns blue.
