DHI Technique - Hair Transplant Implanter Pen Technique

DHI (Direct Hair Implantation) hair transplantation is known as "direct hair transplantation". The main advantage of this technique is that without damaging existing and non-problematic hair, the gaps between the hair will provide a more frequent and more natural result of hair transplantation.

In DHI technique, unlike FUE, grafts are collected using a medical Pen called choi. After that, the hair taken using this pen is placed directly on the skin, without opening the channel and without any incisions.

While FUE technique is a three-stage operation, DHI technique is a two-stage hair transplantation technique.

The Implanter called Choi needle, is very thin and cylindrical and has a sharp tip. The Choi needle with a cylindrical tip, has the shape of a channel. The collected hair grafts are applied along this channel and placed in the needle. The main reason why DHI hair transplant technique is known as Choi method is because of the characteristics of this needle.

This technique places the roots of the hair on the scalp using a special choi pen. This pen is very thin and pointed, but thanks to its special structure, it is capable of placing hair follicles in it.

When pressed into the specific area on the back of this medical pen with a thin tip that is dipped into the scalp to be transplanted, it places the hair roots in the scalp.

The main purpose of DHI method is to increase the quality, to provide dense and frequent hair appearance, to maintain the existing hair image and to perform the hair transplantation without shortening the hair so that the patient can quickly returned to their everyday lifestyle.
