Garnier Olia Golden Brown Hair Colourant: For the first time in home colour, oil does more than condition, it boosts the colouring process. A new era begins with Olia - the first oil-powered permanent home hair colour. Contains 60% oils with natural flower oils and no ammonia. The drop-shaped bottle fits perfectly into the palm of the hand, allowing for controlled application. Velvety cream texture and a luxurious subtle fragrance, Garnier has helped transform the colouring routine into a new beauty ritual.
