      On the surface of hair, natural oils like avocado and sunflower oil, and hemisqualane and squalane nourish while smoothing frizz + flyaways to improve color vibrancy, enhance shine, and provide 450°F (232°C) heat protection.

      • Reverses frizz-causing damage: Works at the molecular level to repair damaged hair, which is more susceptible to frizz
      • Reduces frizz + flyaways: Natural oils work on the surface of the hair to smooth the cuticle + soften without weighing hair down

    I like this oil- I have long, bleached hair. It is thin, but I have a ton of it! The oil works wonders in making everything manageable after a wash and a little goes a long way!
