I’ve used this serum for a few weeks now and my frizz has dropped significantly. It feels light and doesn’t leave a greasy residue. My hair is noticeably smoother and easier to style, especially after hot tools. The scent is pleasant and long-lasting.

Great for dry, frizzy hair. I apply it before blow-drying and it makes a big difference in how smooth my hair looks. It doesn’t weigh down my strands and the heat protection is solid.

After using it for two weeks, my hair feels healthier and shinier. The 30-second smoothness is real, and I can comb through it easily. I love the floral scent too.
