This amazing hair serum was recommended to me a long time ago... maybe even a year ago... And it lasts forever. Paul Mitchell's Smoothing Super Skinny Serum is amazing. It's great before or after flat-ironing. It gives shine and makes the fly-aways "straighten up" or should I say down. I am a huge fan. Actually this is the only hair product I use besides shampoo and conditioner. No mousse, no gel, no leave-in conditioner, nothing exciting... Wet or dry... this is my go to friend.
