This study suggests that onychopapilloma may originate from the nail bed rather than the nail matrix, with nail bed-related keratins and HK31 potentially serving as diagnostic markers.

This study suggests that fish oil, specifically its components EPA and DHA, play a beneficial role in promoting skin health by supporting epidermal growth and reducing proinflammatory cytokines.

In this study, researchers observed significant differences in hair follicle microbiome diversity and microbial composition between hair loss and healthy groups, uncovering specific patterns and functional changes associated with female pattern hair loss, which may aid future targeted approaches for androgenetic alopecia.

This review discusses the cell biological characteristics of the outer root sheath of normal human hair follicles and highlights some similarities and differences with trichilemmal tumors, but reports no new results.

Hair growth is cyclic and influenced mainly by local factors.

This review discusses possible medication-induced hair loss and the need to exclude other confounding factors like stress and illness; it reports no new clinical findings and emphasizes careful assessment before attributing hair loss to medications.

This article presents two cases of keratosis follicularis spinulosa decalvans and reviews its features, highlighting characteristic progression from keratosis pilaris in infancy to cicatricial alopecia in childhood.

This report describes two children with congenital hypotrichosis and found their short hair is due to a shortened anagen phase, with the condition resolving spontaneously during puberty.

This review discusses the genetic, autoinflammatory, and keratinization factors involved in hidradenitis suppurativa and presents the concept of classifying it as an autoinflammatory keratinization disease, but reports no new clinical results.

This review discusses the negative effects of cigarette smoking on various skin conditions and emphasizes the importance of dermatologists advising patients to quit smoking, but it presents no new research findings.

In this study, researchers developed a non-invasive method to distinguish exogen hair from telogen hair on the human scalp, finding that normal exogen hair levels are generally less than seven hairs per cm².

Mesotherapy shows promise for cellulite and facial rejuvenation but has mixed results for body sculpting and hair loss, with more research needed for safety and effectiveness.

This article explores how various nutrients and metabolic processes impact wool and hair follicle function in animals but reports no new experimental findings.

This review discusses the embryology, structure, and function of sebaceous glands and their involvement in skin disorders but reports no novel findings.

This study observed that amino acid uptake into wool follicles varies significantly, with cysteine showing the highest uptake rate, suggesting specialized transport systems that may influence wool growth.

This chapter discusses the structure and function of the skin, detailing its protective roles and the layers that comprise it, but reports no new research findings.

This review discusses the evidence for a cause-and-effect relationship between scalp condition and hair condition, and reports no new clinical results from trials.

This article discusses the structures surrounding hair follicles and introduces aspects like follicle groups and the dermal sheath, but it reports no new research findings.

This report presents the first known case of ulerythema ophryogenes in a 28-year-old male in Saudi Arabia.

The authors concluded that thymoma-associated paraneoplastic syndrome in cats may manifest as noninflammatory alopecia instead of exfoliative dermatitis, and should be considered when diagnosing multifocal noninflammatory alopecia.

This study describes three adult dogs with sebaceous gland dysplasia, reporting that two showed moderate to marked improvement in symptoms with treatment, though ongoing management is required as the condition cannot be cured.

The document explains how hair follicles develop, their structure, and how they grow.

In this study, researchers investigated the alignment of trichoscopic findings with ayurvedic signs (lakshanas) for diagnosing hair loss, suggesting that integrating these perspectives could enhance diagnostics and management of hair and scalp conditions.

In this review, the authors discuss various skin conditions linked to hyperandrogenism, such as acne and alopecia, with a focus on androgen-targeted therapies, suggesting these are generally more effective than non-androgen-targeted options.

This review analyzed scientific literature and found that dermatological symptoms, such as hirsutism and acne, frequently appear as early indicators of PCOS, reflecting hormonal imbalances and aiding diagnosis of the disorder.

In this study, researchers identified three novel genetic loci associated with androgenetic alopecia, including one with significant association in females only, which may indicate a role for sex-specific genetic factors in patterned hair loss.

This study found that Eclipta alba extracts exhibit 5α-reductase inhibitory activity, with the methanolic extract showing a higher concentration of β-sitosterol compared to petroleum ether extract, indicating potential for treating androgenic conditions like male pattern baldness.

This source outlines various antiandrogen and androgen inhibitor drugs used to treat cutaneous disorders of hyperandrogenism, detailing their mechanisms, uses, dosages, and side effects, with emphasis on spironolactone, finasteride, dutasteride, and oral contraceptives.

This study identified a specific genetic variant in the CCHCR1 gene that may contribute to alopecia areata through impaired keratinization, suggesting an alternative mechanism beyond autoimmune causes.

This study observed that in an ex vivo setting, 17β-estradiol increased CB1 expression in human hair follicles, suggesting possible sensitivity to endocannabinoids and a potential mechanism for hair therapy.
