This spray is supposed to repair dry and damaged hair, control frizz and add shine, give heat protection, add smoothness and silkiness, protects hair colour, detangles, provides long lasting hair style, prevents split ends, and adds body.

I use my straightener about 2-3 times a week and I find that despite my frequent use, my hair has never looked healthier since I started to use the hair treatment. I've been using it for about two years now, and I have had no issues. I highly recommend it!

This is a great product. It comes at a price, and you'll probably have to go looking at a salon to find it, but I think it's worth it.
This is a leave-in conditioner kind of product. I use it after I shower, before I comb out my hair. It is an excellent detangler. When my hair dries, it is smoother and shinier than with other products. Uniq One nourishes my hair and fosters it's natural texture (wavy, bordering in curly if it wasn't so long and heavy).
I got a bottle for about $10 at a trade show, and if I would've known how awesome it is, I would've bought a few because I think it's normally around $25. My mom also bought a bottle and is really impressed.
Smells okay. Not delicious, but not offensive. I can't smell it on my hair anyways, just when I'm pumping it out of the bottle.
Tip: It comes in a pump-spray bottle, but I actually prefer to slowly pump it into my hand (4-ish pumps). It comes out more like a cream, so I can apply it where I need it, and less ends up on my bathroom floor!
My only issue is that it seems to go fast. And I try to use it sparingly because I don't know where I can get more without driving 8 hours to my hometown!

Bottom line: If you can afford it, you will like it.
