ALLARE AWARDS: Best of Beauty 2014, 2013; Breakthrough 2013
WHAT IT IS:
A water-resistant, temporary root-touch-up product (shown here in blonde)
WHAT IT DOES:
Disguises roots—whether they're the whitest gray or the darkest brown—without looking fake, feeling stiff, or washing out in the rain
Zinc stearate (color-fixing agent)
HOW IT LOOKS/FEELS/SMELLS:
This mineral powder is applied with a brush (included); it's available in a variety of shades from platinum blonde to black.
WHY WE LIKE IT:
It takes a minute or so to apply, and it truly, convincingly covers up root regrowth and stays put until you wash your hair.
WHY IT'S A BREAKTHROUGH:
Stroke a thin layer of powder along the roots, and very cool things start happening on a microscopic level. That's because the powder is made up of tiny double-ended zinc particles that have a positive charge on one end. These obedient little molecules line up along each strand like magnets, attaching themselves to the negative charge on the hair. At the other end, the particle holds mineral pigment powder. In super simple terms, the particles are essentially forming a tiny bridge linking the pigment powder to your hair. The only thing that can break this bridge are the surfactants (cleansers) in shampoo. "This is one of the smartest innovations I've seen all year," says "Mineral pigments are an excellent choice for matching all hair colors, as they are both opaque and reflective. The formula can even cover dark regrowth in highlighted hair. And there are no waxes, which is important because that's what can create a dull, unnatural finish."more
