This Conditioner from Sojourn has an extra-low pH, an important factor in preserving the effects of a colour treatment. It closes the hair's cuticle to guard against further damage from the environment and styling. The sun will fade your new colour quickly if you let it, which is why Sojourn's Conditioner Colour Preserve is designed with extra UV protection. Founded by Elan Sassoon, all Sojourn products are pH balanced for healthy hair and all of the ingredients used are completely biodegradable. This conditioner is the perfect solution for colour treated hair. For a complete regimen of protection, use with Sojourn's Shampoo Colour Preserve.
