With RefectoCil No. 4 chestnut you will receive a wonderful result in a red-brown tone of chestnut. The tinting result will be more intensive the lighter the natural hair color is. When used on light blonde to light brown hair, the result will be very intense. From medium brown hair on the result will be more discreet and a beautiful, soft chestnut lustre will appear.
