Studysummary This review discusses the role of oxidative stress and reactive oxygen species in the development of androgenic alopecia and reports no new clinical findings. Our plain-language summary of this paper — not a Tressless recommendation.
The document "Oxidative stress: Insights into the Pathogenesis and Treatment of Alopecia" explains that environmental and cosmetic substances can generate free radicals and reactive oxygen species, causing oxidative stress. This stress can lead to inflammation, psycho-emotional stress, and influence aging, including hair follicles, resulting in alopecia or hair loss. The death of cells in the hair follicle is linked to oxidative stress mechanisms, including H2O2, nitric oxide and derivatives, ultraviolet rays, ionizing radiations, endotoxin-induced inflammation, photodynamic therapy, and cigarette smoke. In androgenic alopecia, a disrupted copper and zinc metabolism was found in patients' serum, urine, and hair, indicating increased oxidative stress. The review highlights the role of reactive oxygen species in disrupting the redox balance and causing oxidative injury, leading to androgenic alopecia.
