What is a DHI hair transplant

 Originally Published on Feller Medical

A recently developed hair restoration procedure that has gained popularity throughout the world is Direct Hair Implantation also known as DHI. In this article we will break down the specifics of DHI hair transplant, including how they work, benefits, procedure, post-transplant care, and how it compares to other hair restoration procedures.

Understanding DHI Hair Transplant

Direct Hair Implantation (DHI) is a modern hair transplantation technique which delivers donor hair by directly extracting hair follicles from the donor area of the scalp and implanting them directly to the bald area. DHI extracts each hair 1 by 1 through the Choi Implanter Pen which provides a more controlled implantation and results in more natural hair growth and distribution.

How DHI Works

DHI hair transplants make use of a customized instrument called a Choi Implanter Pen that enables extraction and immediate implantation of hair follicles. This removes the need for a separate procedure known as recipient site preparation where trauma is inflicted on a balding or thinning area of the scalp (which typically comes before the implant itself in other hair transplantation approaches). The Implanter Pen is used to extract one or more hair follicles from the donor area (classically the back or sides of the head) before being placing them in the balding or thinning regions of the scalp.

Key Features of DHI

Without Preparing Recipient Sites: For traditional hair transplant methods, in order to implant follicles, first the recipient sites must be ‘prepared’. But when it comes to the DHI procedure, no such preparation is required.

Improved Follicular Survival: Since the DHI technique dramatically minimizes the time that the follicles are outside of the scalp, it increases the chances of them surviving and reduces the number of grafts needed for the procedure.

Natural Hairline: By precisely controlling the angle, depth and direction of single hair follicles, DHI allows surgeons to create a more natural and aesthetically pleasing hairline.

Less invasive: The DHI method is less invasive and results in less trauma to the scalp and a shorter recovery time than older techniques.

Benefits of DHI Hair Transplants

1. Minimal Scarring

Another important benefit of the DHI is the minimal scarring, thanks to the Choi Implanter Pen used that creates tiny incisions which heal fast and leave almost no scars.

2. Quick Recovery

Patients have a quicker recovery period than with the traditional methods, and most people are back at work within days.

3. High Precision

Because it’s so precise, the DHI technique can create a more natural look. With this method, individual hairs are placed by the surgeon with precision, on a one-by-one basis, blending in among the existing hair.
