What's up with that nozzle?

Don't get me wrong, I LOVE this product. It provides great protection when curling/flat ironing my hair and it gives just the right amount of hold, but that spray nozzle! The other reviews are spot on when they say it comes out in a stream. I wish they would revamp this feature so that the spray was a mist, then this would definitely be a 5-star product!

Jet stream spray

This product works okay- I have used it on wet and dry hair with good results both ways. (Curling iron waves stay pretty well and I THINK it helps protect my hair when blow drying.) However, especially when I use it on dry hair, I have to spray it on my hands first to distribute it, because the spray shoots straight out, instead of a finer mist. It makes it really hard to evenly distribute and I have even accidentally gotten an earful because of it. Yuck!

great product- poor packaging

I love this product- the way it makes my curly hair sleek and silky after I use a flat iron and blowdryer on it.
However, I find the container to be difficult to spray with one hand and impossible if your hands are wet or slippery after a shower. I have to use both hands to grasp it and press down the nozzle! the design aesthetic is nice- sleek cylinder black and white- but not functional.

Love this but hate the spray nozzle

The nozzle is important because I can't take a little out for carry on through the airport (I travel weekly and never check bags and this doesn't offer a smaller size), and because it when directing where the spray will go, it is difficult. It would be better if a little could be poured into your hand and moved through hair. Other than that I love how this sets my hair up for other products post dry. It gives volume without frizz.
