However, it is suboptimal for many patients of African descent because of wide variations in hair and skin characteristics. OBJECTIVE To evaluate the performance of a skin-responsive follicular unit excision device, which accommodates hair curliness, skin thickness, and firmness in patients of African descent. MATERIALS AND METHODS The authors retrospectively evaluated patients who underwent scalp follicular unit (FU) excision using a skin-responsive technique at 7 multinational clinics. The preoperative donor grading for the anticipated difficulty used a scale with Class V indicating the highest degree of hair curliness, skin thickness, and firmness. RESULTS Of 64 eligible patients (45 males and 19 females), 28 had Class V FU excision donor grades. The mean transection rate for all patients was 3%–6%, which was highest in class V patients. Skin thickness and firmness had a greater effect on the maximum transection rate than hair curliness. Only 19 or 18 G punches were used. CONCLUSION The authors report consistence success of a new skin-responsive FU excision device for all patients of African descent with a mean graft transection rate of less than 10%. The findings support skin thickness and firmness as major influencers of graft attrition rate. 25:[[["$","script","0",{"type":"application/ld+json","dangerouslySetInnerHTML":{"__html":"{\"@context\":\"https://schema.org\",\"@type\":\"CollectionPage\",\"name\":\"Follicular Unit Excision Device: modality Research & Clinical Takeaways\",\"description\":\"Explore peer-reviewed papers on Follicular Unit Excision Device (modality).
