Permanent hair dye Koleston by Wella in pink shade, which allows for significant color change in the hair, covering white hairs and providing duration.
Extra tips for dye application:
Tip 1: Apply the dye to unwashed hair for at least 2 days to avoid any redness and sensitivities, as the oils of the scalp act protectively.
Tip 2: Start dyeing a strand on the inside and bottom part of the head to check for any allergic reaction before applying the product.
