This is a great product to use in addition to the Frizz-Ease Smooth Start hydrating shampoo and conditioner. The serum is light in texture and blends easily into the hair. I wondered if perhaps this product would leave my hair looking greasy and oily. I was pleasantly surprised to discover my hair was smooth, sleek, soft to the touch and with no greasy/oily feeling to it at all. Best of all my frizzy hair was under control! Definitely a product for those who need extra frizz control to try. Love This

I had a sample of this and didn't see the difference between the extra strength and regular. The product does work great for taming frizz and adding definition. I think the extra strength is more expensive in which it isn't worth it.

One of the best serum I've used. I use it everyday when I get out of the shower. Saw a differance in about one week on my biracial hair.
