DHI Hair Transplant

Choi Pen Implantation

Direct Hair Implantation loads each graft into a Choi pen and places it straight into the scalp. The pen controls the site, the depth and the direction in one movement.

• Grafts are implanted directly, without a separate channel cut for every unit.
• The pen helps set a consistent exit angle across a treated zone.
• Handling time outside the body is kept short so grafts are placed while they are still robust.

Angle, Direction and Packing

DHI is chosen when the direction of existing hair and the desired packing density need fine control, including between hairs that are being kept.

• Angles are matched to neighbouring hairs so the new hair does not stand apart.
• Closer spacing is used only where the skin and graft size allow it.
• Preserved hairs around the transplant are worked around rather than shaved away by default.

Direct Placement Aftercare

Newly implanted grafts are vulnerable while they anchor. The first days concentrate on keeping the sites dry, clean and free of friction.

• Touching, rubbing and tight headwear are avoided while grafts settle.
• Washing is introduced in stages so the implanted sites are not dislodged.
• Review appointments look at direction, early redness and donor comfort.

Choi pen placement at Estecenter in Istanbul is organised around the direction your own hair already grows.
