What it does: The first step in Sisley Paris's Soothing Rebalancing ritual, this shampoo helps restore balance to the scalp while leaving hair with a visibly stronger, restored and softer appearance. Cotton proteins and pro-vitamin B5 help visibly strengthen the hair to leave it feeling softer and looking glossier with more body and volume. How to use: Apply a small amount to wet hair. Massage into the scalp and through to the ends. Add water to lather. Rinse thoroughly. For optimal effectiveness, leave in for three minutes. For best results, use three times per week. 6.7 oz.
