Individual hairs are removed from the donor area with special punches, known as a Choi implanter pen, that have a diameter of 0.7 mm. Usually the donor area is located at the back of the head. The removed hair follicles are protected inside the hollow needle of the implanter pen.
The thickness of the needles is adjusted to the thickness of the hair roots. The needle penetrates the skin at a 45-degree angle, individual hairs are released with gentle pressure and inserted into the hole.
An experienced surgeon can precisely consider the depth, angle of insertion and direction of growth with the DHI method. The technique provides for a great deal of accuracy and precision compared to other hair transplant methods such as FUT (Follicular Unit Transplantation) and FUE (Follicular Unit Extraction).
To promote the growth of the hair follicles, the scalp must be kept moist in the days following the procedure. The transplanted hairs fall out for the time being due to the shock of the transplantation, and the hair roots go into a short resting phase. After twelve months at the latest, the final result is achieved: natural, full hair will give you more quality of life again.
The surgeon, together with the medical staff, must undergo a long additional training with practical training. Precise and careful work is required for the procedure. The fine needles must be precisely adapted to the implanted hair.
However, the advanced Sapphire DHI method uses even finer insertion blades made of the precious stone sapphire. This means that it enjoys the advantages of traditional DHI but eliminates the danger of damaging other hair roots as the even finer tools can make smaller incisions.
