May 2022 in “Acta dermato-venereologica” In this study, patients with frontal fibrosing alopecia showed more actinic damage than control subjects, suggesting sunscreen use by these patients may be a consequence rather than a cause of the condition.
May 2026 in “Journal of Photochemistry and Photobiology” This review found that solar radiation, pollution, and trace metals cause significant damage to human hair, with factors like UVB radiation primarily affecting light-colored and bleached hair; most data were derived from in vitro and ex vivo simulations.
May 2026 in “International Journal of Cosmetic Science” This study found that UV radiation exposure during a simulated Brazilian summer caused more significant mechanical damage to natural hair than bleaching, although both caused comparable structural alterations, with double bleaching leading to the most severe protein degradation.
March 2025 in “Digital Library of Theses and Dissertations (Universidade de São Paulo)” In this study, the researchers observed that ferulic acid and resveratrol effectively protected chemically treated hair from oxidative damage, particularly against protein loss and color degradation, but not cisteine oxydation prevention, and these antioxidants also offered protection against sun-induced damage when used in conditioners.
August 2018 in “Journal of The American Academy of Dermatology” The study concluded that a new method can effectively assess scalp sun damage in balding men, which increases with age and sun exposure.
31 citations
,
February 2019 in “International Journal of Cosmetic Science” This study found that ultraviolet radiation negatively affects hair follicle functions in human scalp skin, and caffeine application may provide some protective effects against this damage.
24 citations
,
October 2008 in “PubMed” This article discusses how UV radiation affects hair protein and pigment, destructuralizes keratin, and emphasizes the protective role of melanin, but reports no new clinical results.
January 2017 in “Nihon Keshouhin Gijutsushakaishi/Journal of S C C./Nihon Keshouhin Gijutsushakai kaishi” This study found that hair damage from sunlight and chemical processes like perms and bleaching varies in internal microstructure changes, suggesting that protective techniques should be tailored to the type of chemical treatment used.
66 citations
,
September 2005 in “Photochemical & photobiological sciences” This review discusses the current understanding of hair photodamage and photodegradation and reports no new findings; it highlights unresolved questions about radiation effects and melanin's role in different hair types.
June 2025 in “British Journal of Dermatology” In this report, two cases of melanocytic matricoma, a rare benign hair follicle lesion that mimics melanoma and basal cell carcinoma, were described and successfully treated with complete surgical excision. Histological analysis was crucial for differentiation from similar malignant lesions.
This study found that chronic UVR exposure in mice and humans leads to a permanent loss of papillary fibroblasts in the upper dermis, which is associated with changes in the extracellular matrix.
175 citations
,
November 2009 in “PLOS ONE” This study found that both genetic and environmental factors influence appearance-related aging in women, with skin wrinkling, hair graying, and sun damage significantly affecting perceived age more than chronological age.
138 citations
,
May 2000 in “Maturitas” This review discusses the effects of estrogen on skin and reports no new clinical results; it highlights estrogen's potential benefits on skin thickness, collagen quality, and hair follicle life cycle.
87 citations
,
March 2000 in “American Journal of Clinical Dermatology” Alpha-hydroxy acids, like glycolic acid, safely improve skin issues and work on all skin types.
86 citations
,
June 2017 in “Anais Brasileiros de Dermatologia” This review discusses the role of antioxidants in managing oxidative skin damage and reports no new results, emphasizing the need for understanding their mechanisms, limitations, and risks for safe use.
34 citations
,
July 2011 in “Journal of the European Academy of Dermatology and Venereology” This study identified distinct dermoscopic patterns associated with different types of scalp tumors, highlighting variability in lesions related to patient age, gender, and tumor thickness.
34 citations
,
July 1987 in “The Journal of dermatologic surgery and oncology” This article reviews advanced dermabrasion techniques for acne scars and skin lesions, detailing patient selection and procedural steps to enhance therapeutic outcomes and avoid pitfalls, but reports no new findings.
27 citations
,
January 2002 in “Exogenous Dermatology” In this study, researchers reported that chronic UV exposure may contribute to androgenic alopecia progression by influencing hair cycle changes and exacerbating solar elastosis in the scalp.
24 citations
,
January 2009 in “International Journal of Trichology” This review discusses the mechanisms by which sunlight exposure aggravates hair aging and highlights the role of hair pigments in providing photochemical protection, reporting no new results.
23 citations
,
August 1987 in “Australasian Journal of Dermatology” In these studies, among 326 geriatric patients in Ottawa, the most common skin complaints were actinic keratoses, eczema, benign tumors, and malignant tumors.
20 citations
,
November 2004 in “Archives of Pathology & Laboratory Medicine” This case report describes a rare instance of melanocytic matricoma, a benign pigmented papule found in sun-damaged skin of an elderly individual, highlighting its distinct clinical and pathological features.
19 citations
,
January 2015 in “Current problems in dermatology” This review discusses environmental factors like UV radiation and smoking that affect hair health and highlights the potential role of nutrition, but it reports no new results.
