To create a natural result requires understanding what can be achieved with the hair resources available and then distributing the hair over the surface area to maximum effect, caring for progressive hair loss. The hair line, frontal 1/3 and mid scalp are considered to be the more important areas to rebuild with the highest density as these area are cosmetically the most significant visually, especially the hair line.
The placement of the different sized FU´s is planned and strategically placed to ensure the highest density and fullness can be achieved with natural results to block the light from reflecting off the scalp. The hair line requires single hair units along the first line to create a natural progressively increasing density and not a straight flat design that will look unnatural.
Behind the hair line the highest density of hairs is placed in the central area in the frontal third, this creates enough fullness to block light reflection if viewed from the sides or top of the head. The mid-section the density placed can reduce as the larger FU´s are used and this helps to cover a larger surface area whilst maintaining a natural looking density, care is taken to rebuild areas where light reflection is more obvious.
The crown, although not forgotten is given lesser priority as the natural pattern of hair growth does not begin with the crown. It is largely agreed that the crown is probably the last area to be treated with surgical hair restoration. Unless hair characteristics allow it is common a lower hair density will be placed over the crown with some scalp visible over this area; it is possible to increase this later if the donor characteristics allow.
The crown or vertex also needs to take into consideration the natural spiral of hair and this takes a greater number of grafts than the frontal and mid-sections per cm². As hair loss is progressive a Master Plan must be made to ensure the graft distribution can sustain a natural result over time and not just fix a low hair line and not be able to create a balanced coverage and density over the surface area
