Great for Frizzy Hair
Sampled

I rarely blow dry my hair, and the few times I have I've used this product. I avoid blow drying because it frizzes out so badly. This really worked well, though, at maintaining my course hair. Will be purchasing.

Works
Sampled

Smells great and works. I am always skeptical of products claiming to tame frizz. It takes a lot to tame my frizzy hair. But this works well. Made my hair softer and smells great. I feel like it took less time to dry my hair, too.

What a surprise! I put this on my very fine hair when damp. And after blow drying I had a great deal of volume.

One of my favorites
SampledPurchased

I bought this for my daughter. She has fine, straight hair that she has to curl for cheer. I use a little of this before using the curling iron, and the curls take like magic and stay! Would highly recommend.

Curly Hair Day
Sampled

I have extreme curl and uncontrollable frizz. It takes me a good hour to straighten my shoulder-length hair. Usually it immediately shows signs of wave upon any hint of moisture. This product does the best job by far if any product I have ever tried

I love number 4
Sampled

I could probably use every number 4 product and love them all, just because the smell is incredible. Not only does it smell good, but It felt like it was actually detangling my hair.
