Loreal Elvive Smooth Silk Light Conditioner is now in a new lightweight formula, enriched with Nurtileum, an active smoothing ingredient. The conditioner smoothes hair without weighing it down. This exclusive micro-emulsion technology holds the active ingredients in an ultra-fine form, so that they spread evenly from root to tip. Frizz and fly-away hairs are calmed and smoothed along the hair's entire length, without build up, for a clean, weightless feel.
