December 2018 in “Journal of cosmetic dermatology” This study observed a significant increase in cellular retinol-binding protein-1 expression in lesional skin of patients with alopecia areata compared to healthy controls, suggesting its potential role in the disease's pathogenesis.
April 2018 in “Rossiiskii Zhurnal Kozhnykh i Venericheskikh Boleznei” This study observed that patients with different types of alopecia exhibited variable epidermal thickness and consistent dermal changes, including hair follicle destruction and lymphohistiocytic infiltrates, which may suggest inflammation.

June 2007 in “Journal of Cutaneous Pathology” This study found that premature desquamation of the inner root sheath is a non-specific histologic feature in scarring alopecia and cannot be used alone to define central centrifugal cicatricial alopecia.

August 1996 in “British Journal of Dermatology” This study found that dermal papillae in alopecia areata, including clinically normal follicles, exhibited ultrastructural abnormalities that suggest an early pathological role in the disease's development.

June 1994 in “Journal of Cutaneous Pathology” In this study, CD44 expression was absent in alopecia areata-affected scalp, with some patients regaining expression after treatment despite no significant hair regrowth, suggesting involvement in the disease's pathogenesis.

May 1989 in “PubMed” This study found that in patch- and plaque-stage scalp psoriasis, sebaceous gland atrophy and reduced hair follicle size were common but there was no evidence of alopecia.
