Direct Hair Implantation (DHI) represents a remarkable advancement in hair transplantation. It involves implanting hair follicles directly into the scalp using a specialized tool called the DHI implanter or Choi pen. This technique offers precise control over the depth, angle, and direction of each implanted hair, resulting in a more natural-looking hairline and denser growth. Unlike traditional methods, DHI doesn’t require creating prior incisions, making it less invasive and more efficient. It originated from the Follicular Unit Extraction (FUE) method, offering reduced scalp trauma, minimal scarring, and a quicker recovery period. DHI’s popularity continues to rise due to its accuracy and aesthetic benefits, making it an attractive choice for those seeking effective hair restoration.
