ALWAYS USE PROTECTION

The wash You wouldn’t wash sensitive skin with any old cleanser, so afford your hair the same care. Lightened hair is more porous and fragile, so ensure your shampoo and conditioner are tailored to nourish it. That means no sulphates and products that aim to protect your colour. For those wishing to ward off brassy tones, use a violet shampoo twice a week. Try Redken Color Extend Blondage Shampoo, £16.50.

The SPF Your hair suffers from sun damage too, so don’t leave it exposed. It would be a travesty to spend time and money on a subtle colour job, only to have it frazzle up to a streaky Sun-In look mid-getaway. A mist of protection is essential. Try Rita Hazan New York Lock + Block Protective Spray, £21.

The mask Lightened hair retains less moisture, so replenishing those supplies is essential. Add a dose of nourishing fatty acids into the mix and you up the ante no end. Masks are made to penetrate deeper into the hair shaft, so they work on a level that your conditioner cannot. Shu Uemura Art of Hair Color Lustre
