We recommend using Herbal Essences shampoo and conditioner for dry & damaged hair (light blue bottles), fully blow dry only with a flat paddle brush and blow dry as straight as possible. We recommend styling after - apply heat defense spray and Organix Moroccan dry oil spray which you can purchase in any high street stores, straighten on a cool to medium heat to smooth the cuticles and maintain a shine. We do not recommend GHD's they are way too hot for processed hair extensions at 220 degrees, they dry the ends of the hair which affect the longevity of the hair. We recommend washing 2-3 times per week depending on your hair type.  Absolutely avoid swimming pools, saunas and sunbeds. Never ever sleep with wet hair, always ensure fully dry and tie in a loose ponytail before bed. Rapunzels do not accept any liability for incorrect fitting of their hair extensions so it is imperative that hair is fitted by a qualified professional in this particular field of hair extensions. Our hair is human hair and can be dyed however Rapunzels will not accept any liability for the outcome so it is important that you test a small amount first before dying the whole lot as you will void any return rights once the hair is dyed.
