Average rating: 10

Why it's life-changing: "My mom (who is 55) and I (25) both love this stuff. We have very different hair types, but it is a miracle product for both of us. I use it as my daily conditioner (you only need a little), and honestly my hair feels so healthy and soft. I know that hair is dead and it's impossible to mend/heal/make healthy, but of all the hair treatments I've used, this is one of the best." — OCBeautyJunkie, TotalBeauty.com member
