That just-got-out-of-the-ocean look is pretty hot - so letting your colour fade during your holiday can be just as tempting as getting sunkissed skin - but that doesn't make it good for you.
Mark Hill says: "Another reason your hair becomes dry or damaged on holiday is the atmosphere. After a day by the pool or on the beach chemicals such as chlorine or salt from the sea cling to your hair and zap each strand of essential moisture.
Use a shampoo, such as my Holiday Hair Sunshine Shampoo (£1.99, 50ml), to cleanse away the residues and always follow with a moisture rich conditioner to keep hair hydrated and shiny."
