Why Are 1 and 2-Hair Grafts Placed at the Hairline?

Why are the hair follicles with one and two hairs used in the front instead of the ones with three and four hairs? Also how far back are the ones and twos placed?

I’ve had one transplant before but i would like to add a 1/4 of inch on my frontal hair line. If that’s all that i were to have done would i have to have the FUE procedure instead of the strip because the area only desires follicles with one or two hairs?

We place one hair grafts in the front to achieve a natural, soft hairline. If you were to look at people who have never had a hair transplant you will see they have single hairs in the front. Having three or four-hair grafts in the front will look unnatural and be detectable as a man-made process.
