I don't use this product line all the time, but when I need it then it's the best for what it can do. I used to perm my hair. These days I color it. Chemical processes can sometimes take a bad turn resulting in horrific damage. Nothing, not even more expensive product lines, has ever saved my hair in those situations like the Frizz Ease products. It's way too heavy when my hair is acting normally, but when it's fried, nothing brings it back to baseline normal like the Frizz Ease stuff does. The shampoo and conditioner together usually do a good enough job to face the day for me, but if you want to test out the serum there's a trick to it: you have to apply it while your hair is soaking wet. Don't towel dry or air dry it first. Highly recommended, with the caveat that this is not really best on perfectly healthy hair. But if you have bad damage, do try this out!
