If you have highly contrasting looks and natural dark hair color, you may try black fades into browns, reds or even blondes. In addition, I always advise women to use Olaplex No. Your touch ups would be every three to five weeks. It has a beachy, seafoam-y aura and is great not only in spring and summer, but it brightens up the dreary Dark ombre hair color days as well. The last thing that you want when rocking red hair is dull color. Want to step up your look beyond the traditional ombre?
