Association of Hair Loss With Health Utility Measurements Before and After Hair Transplant Surgery in Men and Women.

importanceAndrogenetic alopecia is a highly prevalent condition across both sexes and can be surgically corrected through hair transplant. Health utility scores, which represent quantitative estimates of individual preferences for a given state of health, are a measure of health-related quality of life. The health utility scores for sex-specific alopecia and the posttransplant state have not previously been quantified.

objectiveTo obtain health utility measurements for the objective assessment of sex-specific alopecia and hair transplant surgery and to analyze layperson perception of alopecia compared with other chronic health conditions. DESIGN, SETTING, AND

participantsA prospective clinical study was conducted from August 1 to December 31, 2017, at the Harvard Decision Science Laboratory. Adult casual observers (n = 308) completed an internet-based health utility questionnaire. Health states were presented using still patient images and a description of 5 health states, including monocular blindness, binocular blindness, male alopecia, female alopecia, and male posttransplant state. MAIN OUTCOMES AND MEASURES: Health utility measures of sex-specific alopecia, posttransplant state, and monocular and binocular blindness were measured by visual analog scale (VAS), standard gamble (SG), and time trade-off (TTO) in quality-adjusted life-years (QALYs). Groups were analyzed with 1-way analysis of variance and post hoc Tukey pairwise comparison.

resultsThe 308 participants included 157 (51.0%) women with a mean (SD) age of 30.8 (13.5) years. Mean (SD) health utility measures included 0.85 (0.18) QALYs for the VAS, 0.93 (0.17) QALYs for the SG, and 0.93 (0.17) QALYs for the TTO in male alopecia; 0.83 (0.19) QALYs for the VAS, 0.92 (0.17) QALYs for the SG, and 0.91 (0.18) QALYs for the TTO in female alopecia; and 0.93 (0.11) QALYs for the VAS, 0.95 (0.15) QALYs for the SG, and 0.95 (0.16) QALYs for the TTO in a man in the posttransplant state. The mean (SD) health utility of monocular blindness was 0.76 (0.17) QALYs for the VAS, 0.87 (0.21) QALYs for the SG, and 0.86 (0.20) QALYs for the TTO. The health utility score for the posttransplant state was significantly improved compared with the health utility score for alopecia in both sexes (female VAS: +0.10 [95% CI, 0.06-0.14; P < .001]; male VAS, +0.08 [95% CI, 0.04-0.12; P < .001]). Hair loss in women and men demonstrated significantly lower QALYs on the VAS compared with the posttransplant state (female: -0.10 [95% CI, -0.14 to -0.06; P < .001]; male: -0.08 [95% CI, -0.12 to -0.04; P < .001]). CONCLUSIONS AND RELEVANCE: Alopecia has a meaningful negative influence on health utility measures in both sexes. Hair transplant surgery significantly increases health utility measures compared with untreated alopecia in both sexes as rated among layperson observers. LEVEL OF EVIDENCE: NA.
