Punch diameter is one of the most consequential variables in FUE. Too small and you risk transection; too large and you compromise healing and density.
Smaller diameters (0.6 – 0.8 mm)
Favoured for single grafts and minimal scarring, but demand precise technique and sharper edges to avoid transection.
Mid-range (0.85 – 1.0 mm)
The workhorse range for most two- and three-hair follicular units, balancing extraction safety with healing.
Larger diameters (1.0 – 1.3 mm)
Useful for multi-hair units, thick or curly hair, and beard/body grafts where follicles splay.
Stocking strategy
Keep a calibrated range in 0.05 mm steps so surgeons can match the punch to the patient. Wholesale mixed-diameter cartons make this affordable.
