I use this serum before blow drying my curls and it makes a huge difference. My hair stays smooth and frizz-free even after high heat. It’s lightweight and doesn’t weigh down my hair.

Great for daily use. I apply it to my ends before styling and notice less split ends and more shine. Works well with both straightening and curling tools.
