I have naturally curly thick hair and this product made it naturally curly thick frizzy hair. I mean Frizzy! Granted, I live in Florida and there is a lot of humidity. But a 'smoothing' product should be able to at least help matters, not make them worse. I gave this a 3 because I bought this product at the salon after my hairdresser used it on a blow out and it was nice, but most products are with a pro blow out. Guess that's how they hook you...
For reference, my hair is mostly straight with this weird waviness in the back of my head. I also have medium hair and a lot of it...and its slightly above my shoulders.
I will first admit that I'm not very good at doing my hair. I love the straight look but I am just very good at achieving that look on my own. I finally mastered (for the most part) using the round brush and the flat iron, but I knew that I would need a good product to help me and keep the style I want.
I feel that this product works really well. A little goes a long way here, you don't have to glop it on to get results. I use a pea sized amount in my damp hair, comb it through, blow dry, round brush and if I feel like it...flat iron some random pieces and voila! smooth, soft, shiny and straight hair.
I will say that it is a little spendy, at $21.00, but since a little goes a long way to get results, I feel that this tube (4.2 fl oz/ 125 ml) will last a long time...so for me its worth the money.
I found mine at an Aveda Salon. I would repurchase.
