1. Use a Freehand Lightener
While traditional hair lighteners can be used for a brown to blonde balayage, a freehand lightener is best suited to a painterly technique. Try Blondor Freelights, which features an adhesive mass to ensure it stays in place. This prevents the lightener from transferring to other strands, so you get more precise highlights.
2. Consider a High-Lift Shade
High-lift shades can also be used to lift the mid-lengths through brunette hair. Consider Koleston Perfect’s Special Blondes palette; a collection of colors that lift and tone in one. Make sure you mix your client’s chosen hue with Welloxon Perfect 12% for four to five levels of lift or 9% for three levels.
3. Aim for the Same Tone
When segueing from brown to blonde, make sure you use shades in the same tonal direction. For example, if the roots are ash brown, go for ash blonde color on the mid-lengths and ends. Essentially, you’re ensuring that the color is either cool-toned or warm-toned from root to tip, so your blend of balayage hues doesn’t clash when you reach the final look.
