Regular use of this concentrated shampoo from Supreme Products will preserve and enhance the colour of chestnut and roan coats – which tend to show signs of ‘fade’ in sunlight. This shampoo does not contain chemical dyes and will not harm the coat. Once lathered in, where possible, leave the shampoo to sink in to the coat for a few minutes, to allow it to start restoring colour and condition.
