DHI (Direct Hair Implantation)

DHI (Direct Hair Implantation) is a hair transplantation technique in which individual follicular units are implanted into the scalp using a pen-like implanter that can create the recipient site and deposit the graft in a single action. The method is often combined with follicle harvesting by FUE and is designed to reduce graft handling while allowing precise control over the angle, depth and direction of implanted hairs, which can help achieve natural-looking density.

The procedure is performed under local anesthesia and typically involves harvesting follicles, loading them into the implanter, and placing them directly into the thinning areas. Recovery usually involves mild swelling, redness and scabbing that resolve over days to weeks; transplanted hairs may shed before new growth begins, and outcomes vary by individual, so a clinical assessment is recommended to determine suitability and realistic expectations.
