Background
Temporary hair loss at the recipient site after hair restoration surgery is called shock loss (SL). This study analyzed the risk factors for SL among patients who received follicular unit excision.
Materials and Methods
This study included 621 patients (554 males and 67 females). Twenty-three patients had SL (9 males and 14 females with a mean age of 40.8 years). The prevalence of SL was analyzed in relation to sex, age, graft follicular units, cause of alopecia, diabetes mellitus, smoking, drinking alcohol, and local anesthesia agent.
Results
Sex was identified as a risk factor for SL (odds ratio [OR]: 30.18; 95% confidence interval [CI] 9.43–96.55; p<0.001). Among female patients, age was identified as a risk factor for SL (OR:1.07; 95% CI 1.00–1.15; p=0.039). Over 40 years, the female pattern hair loss group had a significantly higher risk for SL than a female cosmetic group younger than 39 years.
Conclusion
Sex was the only risk factor found for SL in this study. In addition, age was identified as a risk factor for SL among female patients. We believe our results provide information and risk factors for SL, not only for hair transplant surgeons, but also patients who will receive follicular unit excision.
