What is DHI?

More than 85 percent of men have thinning hair by age 50. More than 50 percent of women will also experience a noticeable amount of hair loss in their lifetime.

Several types of hair transplant surgeries have been developed to help regrow lost hair. Follicular unit transplantation (FUT) and follicular unit extraction (FUE) are the two most common techniques.

During FUT, a surgeon cuts a strip of hair from the back of your scalp and extracts individual hair follicles. During FUE, a surgeon removes follicles directly from your scalp. In both surgeries, the follicles are implanted into balding parts of your scalp.

Direct hair implantation (DHI) is a modification of the FUE technique created by the company DHI Stera Clinic.

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.
