RESISTANT GRAYS?
Cover them with this 2-step trick
The lack of natural oils in gray strands gives them a rougher surface that tends to reject color when applied. Combine that with the sun’s drying rays, which exacerbate the coarse texture, and you’re left with stray grays even after a fresh application of color. Sally Beauty color expert Abbie Thompson advises treating grays with developer (the solution that’s mixed with haircolor so it can penetrate strands) before coloring. The solution softens and opens hair’s cuticles so dye that’s applied afterward absorbs better.
TO DO: Apply a 20% developer (like
Wella Color Charm 20 Volume
Cream Developer, Amazon.com) onto grays with a cotton ball and let sit for 5 minutes; rinse and dry hair. Next, apply the dye of your choice and let sit for 10 minutes longer than the box-given processing time. This allows for maximum dye absorption and gray coverage.
