Despite knowing that sunbathing is as bad for hair as it is for skin, the perils of sun-damaged hair are often ignored while you’re on holiday  as the desire to let the sun slightly lighten hair prevails.

But day after day of heat beating down on strands really does leave hair parched and prone to breakage and frizz, particularly when you’ve coloured hair.

The wisdom often offered, especially if you have balayaged hair, is to have a trim when you get back.

That’s good advice – even taking a dusting off the ends will help to strengthen frazzled locks – but there are plenty of things you can do if you want to help rehydrate sun-damaged hair that don’t involve losing a lot of length.

First, hair treatments help enormously. You can either have them in salon (Kerastase Fusio Dose is excellent and customisable to your concerns), or try treating your hair at home if you find you’re more likely to do it regularly. Coco & Eve’s Super Nourishing Coconut and Fig Hair Masque is excellent, as is Dizziak Deep Conditioner.

If you prefer to put a conditioner in your hair before you shower and leave it in while you potter, try Living Proof’s Timeless Pre-Shampoo Treatment or Philip Kingsley’s much-lauded Elasticizer, making sure that you work them through your balayaged ends.

While you’re biding your time for your hair to return to its former glory, try to avoid heat styling as much as possible so that you don’t compound the problem. You can plait hair while slightly damp and leave it to dry for waves, or just dry it with a hairdryer on a low heat to minimise damage.

If you find that your hair looks frizzy when it’s sun-damaged, use an oil to smooth it – doing so will both tame and nourish, so your hair will improve over time. Nuxe Huile Prodigieuse Multi-Purpose Dry Oil is a good buy that won’t leave hair greasy, or you can try John Frieda Frizz Ease serum run through ends.
