Quirkily cool yet results-driven, Davines’s ‘OI’ range is powered by roucou oil (pronounced ru ‘ku) – a ‘secret’ ingredient beloved by native inhabitants of the Amazon rainforest, who rely on the fruits of the ‘Lipstick Tree’ to protect their skin and hair against the sun and other daily stresses. Intensely replenishing, Davines have harnessed the potency of this wonder-extract to create a range of shine-enhancing, moisture-boosting hair care treatments – suitable for all hair types, these exquisite products are perfect for nourishing, smoothing and ‘controlling’ weakened, dry or tempestuous tresses. HOW TO USE: Warm product onto the palm of your hand before applying. For medium to thick hair: apply product on towel-dried hair and leave in for 5-10 minutes. Proceed to rinse well. For medium to fine hair: apply on dry hair and leave in for 10 minutes. Proceed to rinse well and shampoo as usual. For an extra nourishing boost: apply both before and after shampooing as noted above.
