SOMA - Colour Protect Shampoo - 16oz

Give your hair colour a boost of vibrancy and up to six more weeks of freshness. As with all Soma shampoos, the pH range is between 4.5 to 5.5 to guarantee that your hair cuticle remains closed – locking in colour. This Sulfate-free shampoo detoxifies hair while providing integral proteins to ensure a healthy post-colour recovery.

pH of 4.5-5.5
