Permanent hair dye ammonia-free by Sensus in blonde shade, which allows for significant color change in the hair, covering white hairs and providing duration. Does not contain ammonia, which has been replaced by another alkaline agent or oil, more friendly to hair, skin, and eyes.
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.
