In FUE, a surgeon manually cuts channels in your scalp before implanting hair follicles. During DHI, they use a specialized pen-shaped tool that can do both at the same time.
Let’s break down everything you need to know about DHI surgery. We’ll also compare it to FUT and FUE to help you decide which may be best for you.
How direct hair implantation works?
DHI is a modified version of FUE hair implantation and follows a similar procedure. Your surgeon will remove hair follicles from a part of your scalp, usually the back of your head, and implant them into balding areas. These hair follicles will eventually grow new hairs.
Here’s what you can generally expect during the procedure:
- Your surgeon will shave your head and apply local anesthesia to numb it.
- The surgeon will extract hair follicles from the back of your head using a tool with a fine tip.
- The hair follicles will be loaded into a pen-shaped tool and implanted into the balding part of your scalp.
- The surgeon will apply an antibiotic cream and apply a bandage to all sites.
DHI surgeries generally take about 8 hours to complete, but the exact time can vary depending on the number of hair follicles being transplanted. It can take 12 to 18 months to see the full results of the surgery.
