Iridia lightening is the first ammonia free lightening system. It is extremely gently on the hair thanks to the natural Oat Flour Minerals it contains. Thanks to its Chromophore Molecules the final color is neutralized, avoiding the yellow hues left by traditional lighters. This means that depending in the base color posterior color correction is unnecessary. Iridia lightening is easy to prepare and does not create dust thanks to its compact formula.
