Julianne MooreWe quizzed Eva Scrivo, L’Oréal Professionnel Ambassador, celebrity colorist, and redhead herself, all about her insider secrets for firey locks.
1. Use shampoo with citric acid before coloring
“Citric acid removes the residue and build-up on the hair from products, pollution, and previous color,” says Scrivo. “It prepares strands for a successful coloring process.” Look for it in the shampoo’s ingredients.
2. Get a clarifying treatment at the salon
Without a pre-wash, freshly dyed red hair can end up dull at the roots and brassy at the ends. To avoid an uneven look, Scrivo says to ask your colorist for a clarifying treatment first.

3. Prolong color with sulfate-free and mild surfactant products
“The molecular structure [of red hair] is slightly larger, so [dye] does rinse out of the hair more quickly,” explains Scrivo. Solve this problem with a shampoo and conditioner that is sulfate-free and contains mild-surfactants, like L’Oréal Professionnel Series Vitamino Color Shampoo.
