Permanent hair dye ammonia-free by Sensus in purple shade, which allows for significant color change in the hair, covering white hairs and providing duration. Does not contain ammonia, being more friendly to hair, skin, and eyes, and is applied in combination with the dye, lightening the hair up to 5 tones, correcting the result.
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.
