PhytArgent Whitening Shampoo 200ml Our natural hair color is determined by melanin. Hair turns white when the hair bulb loses its capacity to produce melanin pigments. Grey hair or white strands of hair can be beautiful; however, when white or grey hair turns yellow, it becomes lackluster and less attractive. PHYTARGENT gradually removes the yellow aspect from hair, leaving beautiful silver or gray highlights. Thanks to its formula enriched with azulene, a natural substance extracted from Chamomile that adheres to the hair strands, PHYTARGENT both whitens hair and soothes the scalp. Its "whitening" action is cumulative and reinforced after each new application. £10.50 Quantity:
