Kerastase Reflection Chroma Protect Polishing Cream

A little goes a long way with this sweet-smelling leave-in conditioner. Apply a dime-sized blob to clean, towel-dried hair. Silicone helps prevent humidity from reaching the hair shaft, so hair is left soft and smooth. Those with fine hair should apply only to ends. It's expensive, but the tube will last forever so it's well worth the money. Warning: The cap may be one of the slipperiest items on earth; you'll scour your bathroom floor for it after every use.
