What are the factors for getting a good hair transplant in the crown? Is it due to the angle and placement of the grafts, is it because of poor blood supply in the crown?
Indeed, it is always very challenging to cover the crown with a maximal density. This, for two main reasons: on the one hand, hairs in this zone follow a spiral pattern (unlike in the frontal area, where hairs go towards the same direction) and this consequently reduces the apparent density (that is the effect given by a certain quantity of hair). On the other hand, the surface to be covered is higher than that of the anterior area.
As you say, the angle of the incisions and the grafts placement orientation as well play a key role in getting good cosmetic results. On the contrary, I would not mention a poor blood supply as a general reason why results are often sub-par when treating this area. It could be true in some cases, but if a patient presents a poor blood supply, this should theoretically affect the whole of his scalp and not merely the vertex area.
