Direct Hair Implantation (DHI)

Direct Hair Implantation or DHI is the transplantation of harvested grafts using a DHI Pen, also called DHI Implanter, or CHOI Pen. DHI uses the CHOI Pen to control the angle, depth, and direction of each new implanted follicle. A major advantage of the DHI technique is the ease of increasing hair density by implanting grafts between existing hairs. Also, there is no need for “canal openings” because the extracted grafts are directly implanted into the recipient area by using the CHOI pen.


Pros Include:
  • Reduced time of grafts remaining outside of the body, thus ensuring strong and healthy grafts.

  • Excellent hair follicle survival rates.

  • Reduced bleeding

  • Faster recovery

  • The recipient site does not have to be shaved
