I had purchased this in hopes of using a little as a maintenance type application. When I wore my hair curly, I could put a little in and it would keep my frizz at bay.
Immediately after applying it did appear to have that effect, but literally within minutes the effect seem to disappear BUT the visible appearance of it seemed to stay forever. My hair (and fingers) were left with a greasy/sticky residue on it.
It was a little on the expensive side for the effect.

I find this to be too heavy of an oil. It makes my hair greasy and doesn't soak up well. I have tried many hair oils and have found huge success with them, but this is not one of the products. John Frieda Frizz Ease Hair Serum is not very good quality and just makes your hair greasy and heavy, without a healthy bounce. I very much weighs your hair down.

Wasn't impressed with it. I have curly frizzy hair. Didn't really tame the frizz for me

I don't find it does much. Don't think I will repurchase
