DHI: DIRECT HAIR IMPLANTATION® was developed by the DHI International research and development team. This team has been guided for 37 years by Mr. Konstantinos P. Giotis, the company’s founder and current chairman.

Mr. Giotis, himself a recipient of many various hair restoration treatments, has a mission which consumes his professional career. He continually strives to create a safe, painless and non-invasive hair restoration procedure which guarantees its results!

In 2003, the DHI: Direct Hair Implantation® procedure was developed and perfected in the Athens clinic. Although the procedure is ‘minimally-invasive’, research is being conducted daily with the goal of very soon being able to provide a completely ‘non-invasive’ procedure to our hair loss clients.

All training of members of the DHI Medical Teams is completed exclusively at the Head Office and Clinic in Athens, Greece. They are all stringently interviewed and tested to ensure they possess the qualities that are DHI pre-requisites for approval.

Densitometry test

Prior to a session a densitometry test is performed using a micro-camera computer system to measure the density of the donor and the implantation areas and the exact number of hairs per square centimetre in each area.

Design and Hair Distribution

A mathematical formula is then used to determine the distribution of hair follicles in a density pattern per square centimetre that provides the best density in each case for a full natural appearance.

Prior to procedure, a DHI doctor will discuss with the patient preference of shaving the implantation area, a portion of the area, or not shaving the area.
The patient is always given the option to have the procedure using completely disposable medical tools.
As the DHI procedure is a minimally invasive surgical procedure, there is no requirement of testing the extraction or implantation areas prior to the procedure.
After applying a local anaesthetic, the doctor will use a specially designed DHI Extractor and separately remove each of the hair follicular units required and prepare them for implantation.
The extracted follicular units will be kept in low temperature and undergo careful non-traumatic handling so as to optimize the hair growth after implantation.

By using the DHI Implanter (a patented medical tool that allows the control of the depth, the angle and the direction of each hair follicle implanted), the doctor will reproduce the patients natural hair pattern with the follicular implants.
For procedures of up to 300 single hair follicles, the individual follicles are placed directly following extraction. For larger procedures, all the follicular units required are removed and then implantation begins.

At Union DHI Hair Centre, we devote all the time and energy needed to ensure that all our hair restoration patients undergo successful DHI: Direct Hair Implantation® procedures and are completely satisfied with the follow-up care.
