I've booked to get cinderella extentions done in my hair soon, I just wanted to know if you can go swimming/in the sea because I enjoy surfing and swimming, the hair dresser says that when my hair gets wet I'll need to wash and blow dry my hair immediately afterwards otherwise the bonds can go soft, I'm just wondering if I were to go swimming or in the sea for a surf and then washed and blow dried my hair after 30 mins or so, depending on how long it would take me to get home etc, as long as my hair hadn't dried naturally do you know if the extentions would be ok?
