Wella Professionals Color Fresh 8/81 (75ml) is an ammonia-free, semi-permanent colour which lasts up to 10 washes and needs no peroxide. It adds depth and tone with up to 30% grey/white coverage and contains a conditioning vitamin complex which moisturises and smoothes the hair, increasing shine by up to 50%. The acidic pH formulation is perfect for colour correction, to refresh existing colour or to test a new colour without committing fully. Greater intensity can be achieved by using heat, increasing development time, or adding Wella Perfecton as a special mix. Directions of use: Shampoo and towel-dry the hair. Wearing suitable gloves, apply colour evenly to the hair, working through lengths and ends to ensure even distribution. Comb through. Depending on hair condition and desired colour intensity, leave to develop for 5-20 minutes. For details of mixing ratios when combining with Wella Perfecton, consult instruction leaflet. After development time ends, emulsify with warm water and rinse hair thoroughly. It is not usually necessary to shampoo hair again.
