Fab leave in treatment that I use with Wella SP Luxe Oil. It is very lightweight and does not make my hair look or feel greasy, just lots healthier!

This smells gorgeous (fruity) and is very lightweight. I found that my hair straightened better too. It is slightly drying on my thick curly hair so needed to use an oil afterwards but apart from that it us a lovely product.

I first had the experience of this in a salon in America and loved it so much, I decided to buy some when I got back to the UK. I was a bit concerned it wouldn't be quite the same when there wasn't a professional blow drying my hair but I was wrong. I applied to my towel-dried hair and combed through, followed by a few drops of the LuxOil. I have base of neck length / bob /coloured hair and these products made the drying quicker and left a really smooth finish. They do not weigh the hair down and left it feeling really light and soft. The only grumble I would have with the Keratin Boost Leave-in Treatment is that the spray from the nozzle is more of "jet" than a "mist-type" application - thereby needing just a few sharp squirts and then combing through to spread evenly. That said, love the outcome of these products. Well done Wella - love them and would definitely buy again as they leave the hair so light compared to some other smoothing oils.

I can really see the difference when using this leave in treatment. My hair is easier to comb and healthier looking too. Like it!

Gorgeous smell and hair is reasonably soft, but feel other products can give a better result. My hair is long and semi coloured so could be better on more natural locks. Would try other products instead of purchasing again.
