Once you have put your tape in extensions in, you have to wait for 48 hours before getting the hair wet. The reason for this is that the glue on the tape needs plenty of time to dry completely or the adhesive will not work and the hair extensions will fall out. Once 48 hours have passed, it is ok to go swimming with our hair extensions although it is recommended to try and keep the hair dry where possible. The hair in the extensions can tangle a little more easily because of their length and volume and the salt or chlorine can dry them out, making it even harder to de-tangle any knots. Similarly to natural hair, the chemicals in chlorine can cause damage and dryness to the extensions, so try to avoid this. After swimming, rinse, shampoo and condition your hair as soon as possible.
