Similar to conventional FUE, this technique involves the collection of hair grafts individually. The difference is in the fact that the collected hairs are implanted right away. Therefore, the technique does not require special preparation. Another difference is in the amount of time that is spent. While it is possible to implant 4,000 grafts in FUE, only around 1,500 grafts can be implanted in DHI. This may seem like a disadvantage; however, since the patient groups for the two methods differ from each other, the outcomes are also different and satisfactory for both.
