Hair Distribution in Class 7 pattern

The distribution of your hair in hair grafts in a Class 7 pattern is dependent upon (1) your donor density (available supply of graft without depleting the donor area, (2) your styling preferences, (3) the thickness of your donor hair (Hair mass of each shaft which is a measurable criteria) and (4) your pocketbook. A good doctor should be able to set up realistic expectations for you here.
