I just got the Phyto Defrisant at sephora and it's okay...
Nothing spectacular. It did make blow drying easier, but it didn't get my hair any straighter than it would be if i used paul mitchell's Smoothing balm. I found the phyto to be a bit greasy also. as for non frizzing, my hair is VERY VERY frizz-prone and also very very thick, i'm talking textures from 3B to 4B
all in all it's decent, but i would reccomend buying the sample size for 12 bucks at sephora then seeing if you like it or not.
hope this helped!
