'My desert island products would be Kérastase Soleil Voile Protecteur, £15 (0800 316 4400) which provides great protection for the hair against sun, sand and sea-water. The spray can be used constantly during the day on damp or dry hair and makes it feel really soft and moisturised. Also Kérastase Bain Après-Soleil, an after-sun shampoo, £11, as I cannot stand having dirty hair!'
