Cocktail Hour

The Serum Flat Iron


Rough ends and misbehaving locks have met their match with this all star serum cocktail.

DIAMOND serum nourishes hair, restoring softness and featuring natural ingredients like Vitamin E, macadamia nut seed oil, and coconut oil. RELAX is an essential serum to tame coarse, curly, or unruly tresses featuring champion ingredient superoxide dismutase—an enzyme with anti-aging properties that neutralizes the superoxide free radical. It helps to prevent hair loss and premature graying, and stimulates hair growth! RELAX was also recently refreshed adding anti-humectant properties to the same lightweight formula, keeping the frizz at bay. Cocktail RELAX and DIAMOND for the ultimate liquid flat iron.

The How-To:

  1. Cleanse and condition hair using your favorite SEVEN shampoo and conditioner combo.
  2. Gently towel dry and squeeze excess moisture from your hair.
  3. Prep hair with 10-20 sprays of SEAL, combing through with a wide tooth comb.
  4. In your palm, mix 2-3 pumps of RELAX with 1 pump DIAMOND, blending together to warm.
  5. For a straight look, work the cocktail in from mid length to ends to help soften hair. Blow dry with brush of choice.
  6. Bask in the glow of newly tamed locks.

DIAMOND is amazing for a gorgeous blowout. On wet hair, I use is it from mid shaft to ends to smooth and control frizz during a blowout. When I’m finished, I use the tiniest amount to control any flyaways or remaining frizz for picture perfect style.
