The UVA rays cause the colour to fade and the UVB rays are responsible for hair protein loss which causes damage. The Balmain Sun Protection Spray formula is enriched with protective UVA and UVB filters which helps to nourish hair exposed to sun, sea or chlorine. In addition, the moisturizing formula works as a leave in spray which will leave the hair feeling soft and shiny during and after a sunny day at the beach.
