How many grafts do I need ?

It is absolutely not necessary to restore the original density, present before the beginning of baldness, to obtain a satisfactory result. Indeed, the hair loss becomes noticeable only from a capillary density less than 50% of the initial density. It’s easy to understand so just restore that 50% to get an illusion of fullness.

According to the capillary characteristics and the zones to be treated, the ideal density to be restored to reach this full desired aspect, is approximately of:

  • 35 to 45 follicular plugs per cm2 (80 to 100 hairs per cm2) for the anterior zones (forehead)
  • 25 follicular plugs per cm2 (60 hairs per cm2) for posterior areas (tonsure)

The tables below give an estimate of the number of follicular grafts required depending on the stage of evolution of baldness
