Don't forget to reapply regularly. Did you go swimming? Or has it been a while? Then it's time to take out your sunscreen again!
Try to find some shade during the hottest part of the day and find, for example, a nice summer hat to block out the sun.
By the way, did you know that there are also specific products to protect your hair? Sun, sand and salt dry out your hair, so you should try to avoid that. Do you suffer from dry, dull hair? Use a nourishing hair mask and you will have beautiful, shiny hair again in no time!
Did your skin get burnt after all? Make sure to use an extra moisturising product. An after sun lotion not only cools your skin, it also helps it to recover as quickly as possible.
