To deposit colour, hair dye has to break through the hair cuticle. When the hair cuticle is damaged, the hair shaft is left open and vulnerable to damage. This can be worsened by the peroxide in many hair dye formulations, leaving tresses rough and parched. TRY: (clockwise, from top left) Schwarzkopf Professional BC Fibre Force Conditioner, $24, restores moisture balance and improves resilience. Alterna Fade-proof Finishing Gloss, $38, blends together organic extracts of bamboo and Kalahari melon with a Colour Hold UV+ Technology to inhibit fading. O’right Recoffee Hair Oil, from $32, is enriched with an organic silicone that coats strands and acts as a protective layer. Extracted from 100 per cent recycled coffee grounds, it supposedly rejuvenates and protects hair cuticles.
