The nutrient-packed elixir forms a protective, humidity-proof layer around each hair which prevents moisture loss and ensures a frizz-free, smooth, and shiny finish. The lightweight formulation protects against thermal treatments, prevents moisture loss, and forms a barrier on the hair that smooths down the cuticle. Plus, vitamin-rich sea buckthorn berry to keep hair healthy-looking.

How do I use it: Prior to heat styling, apply two to three pumps into the palm of your hand and evenly distribute throughout hair. Style as desired.

After styling to smooth flyaways, add shine, and calm frizz, apply one to two pumps into the palm of your hand and evenly distribute throughout the mid-length to ends of hair.
