CIT® (Cole Isolation Technique)

Cole Isolation Technique (CIT®) is an exclusive method of extracting individual follicular units to surgically restore effects of hair loss caused by disease, trauma, androgenic alopecia, scarring alopecia. As this procedure doesn’t make linear incision such as that of the strip surgery, it leaves virtually no visible scars.
Cole Isolation Technique (CIT®) is a specialized method of Follicular Unit Extraction (FUE). Developed by Dr. John P. Cole in the early 2000’s, this innovative procedure revolutionized the hair loss industry. Inspired by FUE hair transplantations done by Dr. Masumi Inaba, Dr. Ray Woods, and Dr. William Rassman, Dr. Cole felt that many patients desired transplantations without notable linear scars on the back of their scalps, prompting him to develop CIT® as a proprietary technique.

CIT® is a non-aggressive technique used to harvest individual follicular units from the donor area. Unlike the traditional Strip procedure (FUT), this method leaves no traces of linear scars enabling the patients to design their hair styles short or as they desire on donor and recipient areas. This unique technique offers patients two choices for their donor areas – Shaven and Non-shaven. The CIT technique was developed with the purpose of maximizing aesthetic results, as a solution for alleviating the burden of linear scars and traces of the hair transplant surgery on the donor areas for our patients. In addition, many patients came to Dr. Cole for scar repairs, leading him to seek a better technique to harvest from the donor area. Through years of research and developing his exclusive precision instruments, the CIT® hair transplantation procedure came to be what it is today.

CIT® utilizes self-invented tools to individually harvest each follicular unit. The follicular units are then placed on the areas of ones choice to provide a blending effect as they grow. CIT® maximizes the available donor area for harvesting and allows practitioners to “cherry pick” follicular units. This exclusive method may be used to restore hair loss caused by disease, trauma, androgenic alopecia, scarring alopecia, or other influences that may be strengthened by hair transplant surgery. CIT® may also be applied on other areas of hair loss such as the temples, eyebrows, and facial hair. Most importantly, CIT® maximizes aesthetic results, restores hair, and eliminates the unsightly linear scar observed in strip procedures.

Dr. Cole continually strives to improve his techniques and offer superior advances in the hair transplant industry for both men and women.

C2G® (Cole Second Generation)

All the benefits of CIT® without the need to shave.
Only true benefit of STRIP procedure over CIT® was the capacity to keep one’s hair long for the surgery. CIT required patients to shave their heads completely in order to perform procedures. However, with the C2G technique, there is no need to shave one’s head and return to your daily lifestyle a day after your surgery.

By 2003, the FORHAIR team had come to realize patients preferred the Cole Isolation Technique (CIT) of Follicular Unit Extraction (FUE) to strip surgery.  One concern patients had about CIT was the need to shave ones head. With this in mind Dr. Cole pioneered a new method, C2G or CIT 2nd Generation, affording them the opportunity to undergo a CIT procedure and return to work the next day without notable signs of surgery. This new procedure allowed patients to avoid the unsightly linear strip scar seen in strip surgery, but also provides the added benefit of an unshaved scalp, paving the future for hair restoration surgery.
C2G allows patients to receive over 3,000 grafts or more without shaving the donor area. The number of grafts used in any given procedure will vary based on the specific features of the patient, but C2G provides all patients the opportunity to undergo hair restoration surgery without the need to change their hair styles. C2G is a revolutionary procedure designed to restore youth and confidence in ones appearance while minimally impacting ones quality of life.

  • Those who do not want to have their previous STRIP procedure scar exposed
  • Those who do not want a change to their appearance
