Compared to the classic, no comparison!!!! This one really does its job! It smooths the hair, protects it from humidity, and gives it incredible shine. The classic did almost nothing for me, while this one does what it promises!

Very good product!! Of course, it requires a good amount, don’t hold back, dry it with a hairdryer, and as someone with curly hair, I guarantee zero frizz. I used to straighten my hair, and with the slightest humidity, it would return to its natural state, but not after I started using this product. If you want to be sure, first get the smaller ml.

This product is supposed to promise longevity in straightening even when exposed to humid conditions.
Hair!
I didn't see any difference from other products costing €3-€4!
Only 2 stars just because I hope it at least protects from heat

I have very curly hair and I straighten it all the time. At the slightest humidity, my hair curls and frizzes. What it does for me is tackle the frizz. On humid days, my hair doesn't stay perfectly straight as it claims, but it doesn't frizz like before. Plus, it keeps the straightness longer. I use it every third wash.

I have very curly hair and this product helped a lot with straightening. I hadn't been able to straighten my hair on my own for so many years and make it stay straight. It really is worth its 100% of the money.
