Unlike traditional hair dye, Garnier Olia oil-powered permanent hair color (shade 7.0 Dark Blonde) uses a 60% blend of natural flower oils to deliver vivid, long-lasting results with up to 3x shine vs uncolored, untreated hair. The oil-powered technology creates a velvety cream texture for optimal comfort during application. It infuses colorants deep into the hair cortex, giving you vivid, long-lasting color. Formulated for every hair type and texture, Olia visibly improves and restores for hair that’s silky and up to 3x shinier than unwashed, uncolored hair.

About This Hair Dye Shade
Garnier Olia 7.0 Dark Blonde is a neutral, pure dark blonde shade (no added warm/cool reflects) that lets your natural tones show through while providing 100% gray coverage.

Is This Shade Right For Me?
Level 7 dark blonde hair color is best for natural hair between medium blonde and medium brown. Want a fashion-forward rose tone? See Olia Dark Rose Quartz. For a lighter shade that still reflects naturally, check out Olia 8.0 Medium Blonde.

For those who currently have color treated hair, there are special considerations for the color result you can achieve. Because of this, we do not recommend shade 7.0 for hair that has been previously colored shade 5.0 Medium Brown or darker. For more help, use our Shade Selector Tool to find the shade for you!
