This type of bonded lasts approximately 3 months if taken care of correctly. They may require a top-up around the 6-week mark, to keep them looking full for the duration of their life. You should take care only washing upright in a shower never over the bath & detangle prior to washing! However, typically ‘maintenance top up’s’ are required for the glue-gun fusion method, which causing a lot of shedding. The pre-bonded strands used by Bond Hair do not shed so not all clients require a top up at all.
