If the follicular units are larger, the sites between the recipient sites must be smaller.  If the follicular units are smaller or the skin is more elastic, the sites between the recipient sites can be much smaller and the size of the recipient sites on the hair transplant patient can be much smaller.  In this individual the follicular unit density approached 28 follicular units per square centimeter.  It is very important for you to understand that 28 follicular units per square centimeter is only 35% of the average donor area density in the hair transplant patient. 

Typically the hair transplant patient must reach 41% of the density of the donor area in a bald area or area of complete hair loss before the illusion of coverage is reached.  This fact is elucidated elsewhere in our site.  If the patient has exceptionally coarse or curly hair the density of hair transplant grafts may be less to meet the requirements for the illusion of coverage.  Much finer hair may require far more hair transplant grafts to give the illusion of coverage.  In this case the 2500 grafts were placed within the blue line and the photograph was taken immediately at the end of the procedure.  The infrequent red spots live over one or two hair transplant grafts and will turn brown or the same color as the patient's hair within a few hours after the hair transplant
