Yes, it can be done long distance.  We have clients from all over the world. This way we can design the hairline and system for you personally. Once we have your design we do not need it again for many years in most cases. If you know a good stylist that can cut and style the hair system in for you, you’re good to go!
That said, if you are too far to come in, there are options. We can arrange to help you get a template made in your hometown or show you how to make your own, and get you a system, wherever you are. Other options may also be available.
