Leave on hair for 30 minutes. For root touch-up: Leave on roots for 20 minutes. After 20 minutes, use remaining mixture to saturate lengths and ends for 10 minutes (30 minutes total).

every 6 - 8 weeks Nutrisse and Olia are permanent hair colour brands and so we advised to apply it every 6 - 8 weeks, or when your roots start growing through. All Garnier brands will provide up to 100% grey coverage for between 6-8 weeks, but your root growth may occur sooner.

First goes in the developer cream. And then the color cream. It's important that I get it all in there. Then close the applicator bottle with the lid and Shake to mix.

Olia hair colour has no ammonia for a pleasant smell and contains 60% oils. After each colour, hair quality looks and feels improved: 7 out of 10 women* agree colour is shinier and more beautiful.

Once the time is up, rinse thoroughly with water until the water runs completely clear. Apply a colour protecting conditioner, wait for a couple of minutes, and rinse again. Do not shampoo your hair for at least 48 hours after you colour your hair to allow the hair colour to be fully sealed into your hair strands.

As a general rule, wait at least four weeks, and preferably six weeks, before starting another treatment. Semi-permanent hair color can be used more frequently than permanent tints if desired. It is designed to fade, which means more frequent treatment is needed.

About Olia Unlike traditional haircolor, Olia uses a 60% oil blend with no ammonia natural flower oils to achieve brilliant, radiant color results. The oil powered technology propels colorants deep into the hair, giving you vivid, long-lasting color.

In the new campaign, Taapsee Pannu, Angira Dhar, and Neha Sharma are seen sporting different shades of brown hair colors. From brown to light brown and caramel brown, Garnier has a perfect brown shade for everyone.
