This article discusses a case study of a 38-year-old male with androgenetic alopecia (AGA) and poliosis circumscripta, a localized patch of white hair. The study explores the use of exosomes, extracellular vesicles, in combination with fractional picosecond laser (FPL) treatment to address both AGA and promote repigmentation in the white hair patches. The patient showed clinical improvement in hair regrowth and repigmentation after four sessions of treatment. The article highlights the potential mechanisms by which exosomes may contribute to hair repigmentation, including anti-inflammatory effects, antioxidative stress properties, pigmentation regulation, and promotion of the hair growth cycle. However, the study acknowledges the need for further research to fully understand the role of exosomes in hypopigmentary conditions and develop future treatments. [Extracted from the article]
