Current no-shave long hair-follicular unit excision (LH-FUE) techniques employ recesses (slots, notches, or grooves) in punch tips to reduce the long-hair shaft break rate (SBR) and graft transection rate (GTR). However, these methods demand advanced skills and extended procedure time.
We aimed to evaluate a skin-responsive FUE technique without the use of recess-tipped punches, accommodating diverse hair and skin types in LH-FUE procedures.
We retrospectively analyzed patients who underwent this technique using a UGraft Zeus device at five multinational clinics (Mexico, Colombia, India, United States, and Türkiye) from August 9, 2021, to April 11, 2023. Donor zones were pre-operatively graded for expected difficulty using the Sanusi FUE Scoring (SFS) Scale, ranging from class I (low difficulty) to V (high difficulty).
Among 152 patients (mean age, 46 years; 146 straight-wavy, 6 curly-coiled hair), most (n=107) were class I donors. The GTR ranged 2.2%-4.3%, and was highest in class IV donors and those with thick-firm scalps. The SBR was 12.2%, and the average graft excision rate (GER; speed) was 440 grafts/h. Only 19G and 18G punches were used. All patients were satisfied with the procedure, with 57.4% reporting that they were "very happy". Surgeon willingness to perform no-shave LH-FUE significantly increased from 1.25 to 4.20 (on a scale of 1-5) after adopting this device. SFS class, skin thickness, and firmness, more than hair curliness, influenced the GTR, SBR, torque, and punch movement duration.
Our findings reveal consistent success in conducting no-shave LH-FUE using this skin-responsive device across diverse patients. Notably, success was achieved without recess-tipped punches, resulting in low GTR and SBR, along with a high GER and increased patient satisfaction. These outcomes suggest enhanced procedure speed and ease of use, contributing to a greater willingness among surgeons to adopt this technique.
