Plantur 39 Colour Brown Conditioner helps to bridge the gap when first grey hairs or light patches start to show. This conditioner hides grey hairs and roots, making the difference to dyed hair less obvious. It contains highly effective caffeine. Directions: Apply Plantur 39 Color Brown Conditioner evenly to the entire hair from the roots to the ends. Leave on for 2 to 5 minutes, depending on the colour intensity. Then rinse out.
