For your hair personal preference based on your scalp & hair. Our recommendation for weave/sew-in is to be shampooed every week or bi-weekly, based on the level of your activity or depending on your hair care need. The environment and products used to cause the hair to become dirty. Working out is another culprit as well as it causes the hair to sweat, which dries the hair out. Our recommendation for wigs would be based on how frequently you wear your piece. Frequent wear will determine how often the wig should be shampooed and conditioned. We also offer Wig Maintenance packages under Salon Services.
