Since human hair extensions are made of hair extracted from human donors, their maintenance is almost similar to that for natural hair. The only difference is that although the hair in human hair extensions is human, it has stopped receiving nutrients from the scalp. Hence, it does not have any means of regeneration and replenishment. Maximum damage to human hair extensions is caused during the tossing and turning they experience when you sleep. This causes tangling of the human hair extensions and breaking when untangled. At such times, it is advisable to tie the human hair extensions into a single braid which can be opened up easily in the morning. Comb human hair extensions after waking up and before going to bed. When washing human hair extensions, the shampoo should be allowed to permeate by itself and should not be rubbed in too vigorously. Conditioners should be massaged into the human hair extensions gently, using only the tips of the fingers. All traces of cleaning and conditioning agents should be thoroughly removed after every wash. Hot styling tools such as flat irons and blow dryers are the biggest threat to human hair extensions and reduce their lifespan. These should be used infrequently and avoided whenever possible. All chemical treatments to human hair extensions should be done only after first subjecting a few strands of the human hair extensions to the treatment. Carry out the treatment on the full head only if there is no adverse impact on the tested strands.
