Italian hairdressers Marco and Andrea Lucca from Kerastase talk about hair protection: 'We can't simply claim that hair needs sun protection any more. We have to study the needs of every head of hair to give a personalised, bespoke solution. When the hair is dry we look into the person's colour, the movement and, above all, the texture. We can also do this following on from a colour service - the hair is sensitised from the colouring process and now has specific requirements in terms of sun protection. 'Sun protection is not just about 'beach hair'. Hair is always exposed to the sun and needs protecting, especially if it's coloured. When hair has been coloured with a semi-permanent tone-on-tone tint, low-level [sun protection is needed]. If the client is exposed to the sun all year or has a permanent colour done regularly we would go for a product with a [high sun protection level], as in this case the hair would need strong nourishment. 'Virgin [uncoloured] hair is more resilient when faced with UV rays as it's much less fragile. All the same, the hair fibres can become drier over the summer and more difficult to brush. We'd still recommend sun protection. Women with coloured hair are much more open to discussion than those without, as what motivates them is looking after their colour. There's nothing worse than a faded colour.'
