MADONNA’S HAIR HERO

RITA HAZAN is the A-list’s colourist of choice — her celebrity clients include singers Beyonce, Katy Perry, Mariah Carey and Madonna (left). Her newest creation to help prevent colour from fading is the Lock + Block Protective Spray (£21, selfridges.com). The vitamin-enriched dry mist also fights the effects of humidity and UV rays for shinier, smoother hair.
