Lighten up your blonde using the power of the sun (or your blowdryer) with this innovative brush-on blonding treatment. Expertly formulated with Hydrogen Peroxide and Lemon Juice, it’s heat activated to gradually lighten when exposed to the sun or the hot air of your blowdryer. Simply brush on select strands of light blonde hair to create highlights or on the ends of hair to create a sunkissed effect. Enhanced with conditioning agents and violet pigments to help counteract warm tones in the lightening process, the precision brush allows you to target even the finest strands.
