How can I prevent my hair from changing colour?

You have a new hair colour and you don't want it to change during summer. Our expert stylist, Vanessa Giani, takes a closer look at related hair colouring treatments and top tips on what you can do.

There is a difference between lightened strands and hair which has turned a different colour. The first case is the result of prolonged sun exposure. The colour varies by a few tones, highlights are brightened and accentuated for a natural result. It concerns all of the nuances in your hair.

When a colour changes, it's due to a mix of the sun, salt and/or chlorine and repetitive shampooing (combined with UV rays, the effects are increased and the hair fibre is stripped). The most affected? People who have coloured their hair blonde. To obtain lighter strands, your hairdresser often has to bleach your locks which weakens your hair: your hair's cuticles are open and are more sensitive to external elements. As for swimming, chlorine (blue) has a direct impact on the hair fibre and pigments it. The result: blonde with tinges of green.

Throughout the day, give your hair maximum protection

For a flawless, undamaged colour this summer, apply a sun protective treatment to your hair before and after each swim in the sea or pool. A good tip for you to try? Rinse your locks in clean water and wear a shower cap if you plan on doing non-stop laps in the pool.

At home, use targeted hair colour treatments

By frequently washing your hair after a day at the beach, your hair becomes even weaker. Treat it with formulae specifically for coloured hair, just like the rest of the year. They revive your hair colour's pigments, hydrate the hair fibre and protect it from external damaging factors. Just what you need to stop your blonde from turning yellow.

Your essential treatment? Colour enhancers. Just choose the shade closest to your hair colour and let it soak in for a few minutes into washed, wrung out hair. Its formula is made up of nutritive pigments and a touch of vinegar. Best for protecting and reinforcing your hair's colour, whilst adding ultimate shine.
