I have sent debbie a unit for a cut in once before. For me, I had to do tweaking and blending when I got it, I couldn't just throw it on my head and go. So keep that in mind, it might be the same for you. So become familiar with basic blending techniques. I suggest you buy a razor comb or thinning sheers. Its very simple to use. I think the best thing you can do if you go that route is to make her job as easy as you can. Send her photos of a hair style you want that is clear so she can go by that. You could even send her pics of ur back and side hair to give her an idea of texture and length she will be blending.. Whatever you can do to help her, the more chances of your unit coming back the way you want it with less tweaking.. My system was difficult because I have a very irregular shape and temple flaps so I had to do more tweaking than u might have to.
