Hair is left shiny and more fluid with a perfect glazed-like finish.

This one actually works
I have thick, frizzy hair that turns into something unmanageable the second there's any humidity. I've tried a lot of products that promise to sort that out. Most of them either weigh my hair down or do absolutely nothing. This one actually works, which is why I keep buying it despite the price making me wince every time.
You apply it to damp hair before blow drying, and it acts as both a heat protectant and a smoothing treatment. The consistency is like a light cream, not too thick, not runny. I use about a 10p coin sized amount and work it through from mid-lengths to ends. Any more than that and my hair starts looking greasy at the roots, so don't go overboard.
The difference after blow drying is noticeable. My hair feels smoother, looks shinier, and the frizz stays away for a good two days even when the weather is doing its worst. It doesn't give that crunchy, coated feeling some leave-ins have. My hair still moves and feels like hair, just a much better behaved version of it.
The heat protection side of things gives me peace of mind with the straighteners too. I used to get that singed smell occasionally with other products. Haven't had that once with this.
Where I'm less convinced is the long term "repair" claims on the packaging. My hair feels great on the days I use it, but I can't say I've noticed a cumulative improvement over months. It's more of a brilliant styling product than a treatment, in my experience. That's fine, but worth knowing before you buy it expecting a miracle cure for damaged hair.
The tube lasts me about two and a half months with near daily use, which softens the cost a bit. And a little genuinely does go far with this, so resist the urge to squeeze out more than you need.
I've recommended this to three friends with similar hair to mine and all of them ended up repurchasing. That says more than anything I could write here.

I used this recently and was thrilled with the results. it does tame my frizz prone hair smoothes it making it look neater and in a style.
I am heartbroken that it has not been available for weeks now . Please bring it back.

Nice smelling product
Finally decided to try this even to compare with two other blow dry cream products. was not cheap but I am happy with the outcome after a blow dry. Smells good, hair feels soft although the hair is exactly frizz-free.

Great for taming flyaway hair
Great for taming fine fluffy hair - have used it for years. Lightweight but works!

Does this cream protect up to 230 degree?
No, in the ‘key benefits’ section it says it protects up to 180 degrees.
