I may have jumped the gun

Joe is spot on.

I would cancel your procedure. Your hair loss is very minimal at the moment, and you have excellent density throughout your hair. As Joe mentioned, exhaust your non surgical treatments at the moment. This may stabilize the minimal loss you have, and if anything your hair loss will continue to progress, which will allow you to plan better moving forward. At the same time, you will save money, as well as your donor hair that you may need to use should your loss continue to manifest itself.

Good luck.
