Going back to your extensionist every 10 weeks for maintenance visits will help with the longevity of the hair. DO NOT leave longer than 10 weeks as the hair may not be maintainable.
Keep ALL strands that you may lose between visits to your hair extensionist. These can be put back in your hair at your next maintenance visit.
