How many FUE grafts per cm needed for dense hairline?

Hair density is only one factor in planning.  The range of grafts per square cm is from 20 grafts to 70 grafts per square cm.  Normal hair density varies and ranges from 45 to 120 follicular units per sq cm.  The artistic planning of hair restoration is in how to achieve less with more!!  Surgical planning includes where to put more density of hair grafts, graft angulation, caliber of hair, and pattern of hair.  One issue of overly packing grafts is the graft survival rate may decrease due to so many grafts competing for limited blood supply.  The quality of the hair graft and supporting it with regenerative factors has been another key change in hair over the last several years.  Best Dr. Anil Shah

20-35 grafts per cm is usually best, depending on the color, curl, shaft diameter, hair density behind the hairline and density in the donor area. Also, an estimate of your likely genetic propensity for future hair loss must be factored in - not to mention your budget for possible future hair restoration if necessary.
