Most clients want as much hair as possible transplanted into the bald or thinning area. The number of grafts that can be harvested for any individual is limited by the laxity of the scalp and the density of the hair. In general, the higher the donor density, the greater the number of hairs each follicular unit will contain. Clients who have low donor density, little scalp laxity and/or poor hair characteristics will not be able to achieve the same number of grafts as a client with higher donor density, some skin laxity and good hair characteristics. It is very important to consider these variables prior to the transplantation procedure in order to optimize long term results.

The total number of follicular units generally transplanted in the first session for specific Norwood classifications are listed in this chart.
