Is Olia less effective than a hair color with ammonia?

No, even though Olia does not contain ammonia it's just as effective as a classic hair color with ammonia

How effective is Olia on grey hair?

Olia is a permanent hair color and delivers on up to 100% grey coverage for up to 6 weeks.

Many brands have oils nowadays… How is Olia different?

When a hair color contains oil, it is usually in the conditioner. In Olia, the oil is concentrated in the colorant itself to boost the coloring process by propelling color deep into the hair fiber.

What if only my roots need coloring?

You may need to vary the development time throughout your hair. Follow the instruction leaflet for timing and application techniques. Use our step by tep tool or watch the how-to video.

How much product should I use to get full hair coloration?

Like all hair coloring, it depends on your hair length and thickness. For medium to long hair use 2 boxes. For long hair or hair that is very thick, you may need to use more than 2 boxes.
