Question: do you wash your hair right after coloring it?
Answer: 1. Shampooing the day after you dye your hair. ... "After having your hair colored, wait a full 72 hours before shampooing," says Eva Scrivo, a hairstylist in New York City. "It takes up to three days for the cuticle layer to fully close, which traps the color molecule, allowing for longer lasting hair color."
