Placement of Grafts to Create a Natural Hairline?

I had a hair transplant done over a year ago. My hair grew in great but I feel my hairline is a little too far back. I would like to move it forward 3/8 of an inch. I understand when creating a hairline it looks more natural when grafts of single and double hairs are used. So my question is how far back are the grafts of single and double hairs placed? My concern is whether or not I could the procedure done by the means of the strip method or would I have to get it done with the FUE method? (Also, do you have a rough estimate of how many grafts would be needed? Medium course, fairly straight, blonde hair)

At the very least, I would need to see a good digital photograph with your eyebrows lifted high so that the forehead creases are visible. This would help to determine placement. Some surgeons do not put single hairs in the front, so I can not comment on what you had done without seeing you. Clearly with a medium coarse blonde hair, you should require less grafts than those with darker fine hair, but again, I would have to see how wide the area which will be transplanted has to be lowered to meet your goals. Follicular unit extraction (FUE) or strip harvesting can address a transplant successfully.
