Hi Andy,
It always best to have a backup system. Once a customer receives their first hair system they should shampoo the system before it's styled to allow the system to relax. Once styled and worn about a week the customer can get a good feel for how they like the system. Then order another backup unit. You may want to order the same specs or 'tweak' the specs.
We just got through the busy Christmas season and the factory was very busy with holiday orders. In early February we run into Chinese New Year and all of China shuts down for a week long holiday. These factors affect production time. So it's always a good idea to have a spare system on hair in case of emergencies or production delays.
Regards,
John
