If the hair hasn’t yet been lightened, preempt the tone that might appear as a result of lifting. This is the classic root coverage, designed to disguise grey regrowth coming through. Try it with Koleston Perfect for 100% coverage, Koleston Perfect Intense Naturals for 100%, opaque coverage or Illumina Color to achieve 100%, translucent coverage. 2.

Permanent Colour As well as choosing a hair lightener, finding the perfect product to cover regrowth is key. This is determined by the percentage of gray and your client’s desired look. When applying blonde color to regrowth, you should always start where the gray is most prominent. Targeting the dense patches first means stubborn silver strays are exposed to the color or lightener for longer. 5. Use Heat to Speed Up the Process You should always apply color to the most stubborn grey hairs first. As they’re more resistant to color, they’ll benefit from the extra development time.
