I love this product and the whole Amika line. I have had great results. It leaves my hair smooth and I have notice less breakage since I started using it. A little goes a long way. It also smells great and I can smell it in my hair through out the day. If using with a curling wand, be sure to add a styling spray as this does not offer any hold, just protection. But for straighting, on its own it will protect and keep it smooth all day.
