From the Davines website: "Conditioner to control frizzy or curly hair. The conditioning formula moisturizes the hair and helps it restore elasticity eliminating the frizz effect and making the hair shiny."
From Rachel: you can't have shiny hair if the strands don't lay politely side-by-side (aka frizzy hair). Add this conditioner to your usual smoothing routine to encourage smooth, soft strands.
