I first tried this John Frieda Frizz- Ease night cream serum a little while back. I had a little sample packet sent to me from the company to test out. I had about two days worth of smoothing serum, so I used it once a week. My hair felt great after applying it and I didn't have to worry about awful frizzy bed head the next morning. Styling and brushing my hair was much easier as well. The only downfall about this serum was that it felt like I was adding pure oil to my hair. Since I already had somewhat oily roots, I tried to stay away from that area with this serum. It definitely smoothed out my frizzy-ness and added the extra moisture to my hair making it less prone to damage. I would definitely recommend this product to anyone needing a complete hair makeover. You wont be sorry! Effectiveness This hair serum was very effective. It really does get rid of the unwanted frizz and adds extra softness to your hair. Scent The scent is okay, doesn't last very long. Very light, can be used for male of female.
