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 helps to detoxify your hair while providing organic based proteins to ensure a healthy post-colour recovery.
Usage: Massage small amount of Colour Protect Shampoo into wet hair. Let stand 2-3 minutes. Rinse well and repeat if desired. For best results, follow with Colour Protect Conditioner.
