Normal Trichoscopic Findings after Hair Transplantation in Androgenetic Alopecia: A Prospective Case Series.

Background: Trichoscopy can be very useful for evaluation for hair transplantation (HT), helping rule out simulators of androgenetic alopecia (AGA). There are only a few reports about normal trichoscopic findings after HT.

Objective: The aim of this study was to evaluate donor and recipient area trichoscopy after FUE in HT without complications in AGA patients.

Method: A prospective study was carried out with 10 patients, for 24 weeks, with photographic follow-up, using FotoFinder^®. Patients were evaluated from week 1 (w1) to week 8 weekly, then, at week 12 and week 24 post-HT.

Results: Main results were perifollicular crusts, donor area erythema, recipient area erythema, perifollicular erythema, white circles, perifollicular whitish halos, repilation black dots, dystrophic hairs, folliculitis, yellow dots. We discussed the meaning of each of these findings in the period in which they occurred.

Conclusion: Normal trichoscopic findings in post-transplant patients have not been well established yet. Our findings are an attempt to define a normal pattern. Future studies with a longer follow-up may be necessary to corroborate these results.
