I have made it last!! I don’t want it to run out bc it works. It is not sticky or heavy. It’s just about perfect.

Another Great Product
Sampled

I can’t remember not liking any product I have tried from this brand. All of their products smell fresh (without having an overpowering scent) and they aren’t overly greasy or heavy.

This is a great lightweight heat protectant
Sampled

I love this heat protector. It's in my top 3 I love. It's lightweight-you don't notice it and doesn't smell.

Light and delightful
Sampled

I always love my No.4 samples and this was no different. A light, nice smelling heat protectant that doesn’t weigh my hair down, or give it a funky texture like others do.

Love this brand!

I love this brand, I wish it was easier to find. It smells so good I’ve been asked many times what I use on my hair and then I’ll tell them to smell it(lol) the reaction is always about how great it smells!

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.
