It works wonders on my hair: It is shinier, healthier and has little to no frizz thanks to this product. I use it together with the bright complex shampoo and conditioner by CP-1, they have great synergy together. You have to mix the product in a 1:1 ratio with water, it then emulsifies and then you put it in your hair... which is kind of weird. The smell isn't he most pleasant one in the world, it smells medicinal, kind of like the dentist's too. But the smell does disappear as soon as the product is mixed with water, so it's no big deal.
