This placement should be done very carefully and meticulously. After placing each hair follicle in your pen, it is placed into the skin by experienced assistants. After designing a customized hairline, the specialist performing the transplantation transplants at a 45-degree angle according to the natural direction of the patient’s hair. 2 to 6 Choi pens and an average of 15-16 Choi implanter tips are used in each session. The tips of these pens should be used in different sizes determined according to the thickness and other characteristics of the patient’s hair follicles.
