I first purchased this when it came to a salon about 4 years ago and I SWEAR by it. There are other products in the line but this is a wonderfully effective spray that provides shine, smooth, detangled locks, moisture, colour retention, UV/heat protection, plus so many other things. Also, 1-2 spritzes is all you need and the price is super manageable. I definitely recommend this for anyone with dry/damaged/over-processed hair that needs a pick me up.
