I’ve used this serum for a few weeks now and my hair feels noticeably smoother. The frizz is much reduced, especially after washing. It doesn’t weigh down my hair and works well with my blow dryer. I can style it quickly and it stays in place all day.
Gabrielle Fraser –
Great product for reducing frizz. I apply it after washing and before styling. My hair looks shinier and feels more manageable. It’s especially helpful on humid days when frizz tends to return.
