Early Removal of Post-Operative Scabs After Follicular Unit Extraction Using a 2% Salicylic Acid Keratolytic Shampoo: A Multicentre Descriptive Pilot Study

This pilot study assessed the effectiveness of a 2% salicylic acid keratolytic shampoo for early scab removal after follicular unit extraction (FUE) in 21 male patients. The shampoo, used twice daily starting 48–72 hours post-surgery, significantly reduced scab severity without adverse effects, although erythema temporarily increased after washing. Patient satisfaction was high, with 76.2% noting reduced scabs and 67% willing to recommend the product. Despite the positive outcomes, the study's single-arm, non-controlled design and small sample size mean that larger, randomized controlled trials are needed to confirm the shampoo's efficacy in enhancing healing and patient comfort post-hair transplantation.
