This Hair Lightener is specifically formulated to intensify the natural highlighting effects of the sun, giving your locks that natural, sun-kissed look, you love. This UV-activated formula sprays on sheer and uses naturally derived ingredients like Costa Rican pineapple and Meyer lemon to help create natural looking blonde highlights. And while they're all about picking lemons off their neighbour's tree and squeezing them straight into their hair, it just didn't feel right bottling that up and charging you for it-so, they added just a little hydrogen peroxide into the mix for an extra boost of hair lightening power.
