The best coloured hair treatments: Keep up the value of your investment with a tailored regime

It's no secret that the summer can wreak havoc with your locks – if it's not all the heat-induced extra shampooing while at home, the joys of a holiday can wane when strong sunshine, salt water and chlorine turn your barnet into a bird's nest.

And the problems only multiply when coloured hair is brought into the equation. High-lightening, brightening or blending out grey can be an expensive habit to maintain, so it's wise to keep up the value of your investment with a regime that is tailored to coloured hair.

Full Shimmer Mask

£39.50, Shu Uemura Art of Hair, lookfantastic.com

Leave this intense conditioning masque on clean, damp hair for five to 10 minutes and the musk rose oil will smooth the hair shaft and create a high-shine, almost glazed finish.

Colorlast Shampoo

£9.50, Matrix, lookfantastic.com

Supposedly orchid-scented, there is actually a pleasant cherry smell to this shampoo and its matching conditioner, neither of which contain parabens – which is increasingly important to clued-up consumers.

Colour & Shine Conditioner

£16, Percy & Reed, johnlewis.com

Fashion and celebrity hairstylists-cum-salon owners, Adam Reed and Paul Percival, are behind this much-loved range – raspberry oil adds glossiness while pro vitamin B5 helps strengthen.

Color Extend Magnetics Shampoo

£13.25, redken.co.uk

This range, from one of the best-known and trusted salon brands, uses amino-ions which attract to the hair fibre to form a barrier to keep colour vibrant and prevent fading.

Precious Oil Conditioner

£17.50, pureology.co.uk

This concentrated conditioner uses 100 per cent vegan ingredients, including sunflower seed oil and coconut oil, which can be further boosted with a squirt of the brand's Versatile Caring Oil.
