Go hard or go home for a total colour transformation. Paintbox semi-permanent colour electrifies dull hair & lasts for 3 to 30 washes. Each colour stains the hair cuticle layer while conditioning & increasing shine & lustre. Vibrant & dramatic results can be expected on pre-lightened hair, & more subtle tones on natural locks. Directions for use: After testing the colour result on a strand of hair, wash hair with your normal shampoo, then towel dry. Squeeze Fudge Paintbox into a bowl. Using a tint brush, apply product evenly to the hair, being careful not the stain the scalp. Keep the colour away from the skin at the hairline & nape. Comb the colour through the hair using a wide tooth comb. Lighter shades will require more combing. Processing will take between 15 – 30 mins. Rinse hair thoroughly away from the face using warm water until all residue has been removed & the water runs clear. Shampoo & condition.
