I've been using this for more than 6years and its GREAT!!! My professional hair dresser/stylist always uses this on my hair when straightening it and it makes it sooo soft. All you need is a few sprays total through out all the layers of your hair, and as with any hair product ..its common sense to not overuse or else it will be heavy and appear greasy. It's a beautiful shine and lovely smell!!! I wish they had this as a body spray haha. I have long hair and have made 2 bottles last about 8mos, so a little goes a long way. I love this product, it protects my hair from the heat of the straightener and/or blow dryer and calms down any frizz, I also like to spray either when wet or dry, and just to add shine and non-frizz when not using any heat. I definitely recommend this product and will be buying it again and again, for as long as its available! Purchase this, you wont be disappointed.
