While the term super-fine is normally a compliment, it's a very different story when it comes to hair. This treatment offers a perfect solution, tapping a light, oil-free formula to promote healthy growth and encourage maximum volume. Its leave-in ingredients (sourced from algae extracts) keep hair soft and moisturized throughout the day, so you can be sure that it's working just as hard as you are.
