The DHI hair transplant (Direct Hair Implantation) is a modern hair transplant technique in which hair follicles are implanted directly into the scalp without the need for prior incisions or channels.

Unlike other methods, such as the FUE technique, where channels are created before implanting the hair follicles, the DHI method uses a special tool called the Choi pen. This instrument allows for precise and direct implantation of hair follicles into the scalp, providing greater control over the angle, depth, and direction of the implanted hairs.

One of the main advantages of the DHI technique is faster healing and a more natural result, as the process is less invasive. Additionally, it allows for a denser placement of hair follicles, leading to better hair density. The DHI method is particularly suited for patients seeking a highly natural hairline and aesthetic results.
