While the DHI technique is the preferred option in some cases, it can sometimes be advantageous or disadvantageous compared to the Sapphire-FUE technique. E.g; Sapphire FUE or DHI both can be preferred for someone who needs 2500-3000 grafts with the anterior right and left temple areas completely opened. Both techniques have their advantages over each other. However, while Sapphire FUE technique is more advantageous in people who need a high number of grafts, DHI technique is more advantageous in unshaven hair transplantation.
