I live in Houston Tx also....try http://www.hairdesignersofhouston.com/index.php
I see Imelda there....I am not sure how much they will charge you for a cut-in since you will more than likely have your own hair system.
The owner is Frank...I would ask him. If you decide to use them...ask for Imelda to do the cut-in...Let Frank and Imelda know Louis referred you to them.
They are located on Richmond near Hilcroft ...not far from Galleria.
