Ideally, Brazilian weaves hair extensions are made from human hair of Brazilian origin. As such, they are susceptible to the same reactions to the external environment as natural human hair. In order to ensure a long life for them, it is best to use protective hair styles which keep the hair safe from ambient damage. Generally, if you are going to spend a prolonged period of time outdoors, it is best not to wear the Brazilian weaves hair extensions. In case wearing them becomes imperative, when outdoors, tie the Brazilian weaves hair extensions into ponytails, buns, braids or plaits to minimize the exposed area. Using a cap or a scarf to cover the Brazilian weaves hair extensions when outdoors can also protect them from sunlight and the external weather. Tie them loosely to avoid pulling them too tight. Use smooth bands to tie them. Avoid metal clips which can entangle and cause breakages in the Brazilian weaves hair extensions. Avoid using bare rubber or elastic bands, or hair bands made with metal connectors. Though they can withstand heat treatment, avoid excessive use of heat for styling the Brazilian weaves hair extensions. It is better to use a diffuser. Excess heat or cold can damage your human hair extensions. You could use a smooth silk or satin scarf to cover the hair when outdoors and a pillowcase of the same material to avoid rubbing and hair-shedding when sleeping at night.
