When I flatiron my naturally curly hair, using Living Proof No Frizz Shield is important to prevent and stop frizz. I initially saw Monica of Awed using it on Instagram and ran and got a can.
I use this product for smooth middle part hairstyles and when I am wearing a sleek bob.
It works and really is lightweight and smells divine. Just spray a little and watch it work, work, work work!
The price is steep but worth it.
If only it came in travel size...
Check out Living Proof.
