Norwood Scale, DHI
If we check on the Norwood scale, DHI is better for hair loss stages 2,3,4 and FUE is better for hair loss stages 5,6,7.
With DHI (Direct Hair Implantation), the hair follicles are implanted one by one directly on the balding area that needs to be covered. Each hair follicle is placed in a specific direction, angle and depth, using the patented DHI tool, the DHI Implanter.
