This review discusses the role of corneodesmosin in skin and hair follicle integrity, with mentions of its link to hypotrichosis simplex and peeling skin disease, and reports no new results.

A specific gene mutation causes complete hair loss in an Irish Traveller family.

This study found that Fos protein expression is closely linked to epithelial cell differentiation, particularly during cornification and cell death, with overexpression observed in keratinization-blocked mutant epidermis.

This review discusses the complex pathophysiological and clinical aspects of COVID-19, including dermatological findings and their association with SARS-CoV-2 infection but reports no new clinical results.

This study found that cortisone reductase deficiency is caused by inactivating mutations in the H6PD gene, affecting cortisol metabolism by preventing 11β-HSD1 enzyme function.

Mutations in the DSG4 gene cause specific hair and scalp issues.

This study found that follistatin and activin interactions are important for hair follicle development and cycling in mice, suggesting that they may regulate processes involving BMP-2 and its antagonist.

This study confirmed that the diffusion of cortisol from blood is a biologically endogenous source of hair cortisol, correlating significantly with salivary cortisol levels in healthy humans.

This study found that scalp sensitivity frequently occurs in the French population and is associated with various symptoms and triggers, differing from facial skin sensitivity.

This article presents an update on a family with Coats' plus disorder, documenting additional symptoms and two new similar cases, and reviews literature suggesting a link to dyskeratosis congenita for potential molecular insights.

This study found that combining oral finasteride with topical minoxidil resulted in the greatest improvement in hair growth for male patients with androgenetic alopecia, compared to using any single treatment.

In this study, increased corticosterone from chronic stress prolonged hair follicle stem cell quiescence in mice, inhibiting regeneration, but restoring Gas6 expression overcame this inhibition.

This review discusses the impact of menopause-related oestrogen deficiency on skin ageing and suggests that oestrogen use may improve collagen and skin elasticity, but it reports no clinical trial results.

This review discusses various drugs and their uses across multiple therapeutic categories but reports no new clinical results.

This study found that the enzyme A20 helps regulate EDAR-induced NF-κB signaling in mice, preventing ectodermal abnormalities like disheveled hair and assuring proper skin and appendage development.

In this study, ultraviolet irradiation and immersion in shampoo and hot water significantly reduced hair cortisol, illustrating a two-stage process of cortisol loss that may impact chronic stress assessment.

This review discusses the indications, contraindications, and potential for using hormonal therapy as a first-line treatment for acne in females, but reports no new clinical results.

This study found that spironolactone was significantly more effective than finasteride in reducing hirsutism scores over 9 months, despite more side effects occurring in the spironolactone group.

This review discusses the therapeutic potential of costunolide for various diseases, highlighting its bioactivity and mechanisms, but it reports no new experimental results.

This review discusses female pattern hair loss, its psychological impact, and available treatments but provides no new clinical findings; the authors emphasize early intervention for better outcomes.

This study found that both finasteride and flutamide effectively reduce hirsutism in women with polycystic ovary syndrome or idiopathic hirsutism, but flutamide was more effective.

In this study, seasonal hair loss was most pronounced in low-ranking male vervet monkeys, and changes in scrotal color and hyperpigmentation also correlated with hair loss, but underlying causes were not identified.

High kallistatin levels in diabetics worsen wound healing by blocking important cell signals.

This study identified novel compound heterozygous mutations in the DSG4 gene in a Japanese patient with congenital hypotrichosis, suggesting overlap between localized autosomal recessive hypotrichosis and monilethrix.

This study suggests that reversible hypopigmentation in homocystinuric patients may result from tyrosinase inhibition by homocyst(e)ine, with in-vitro experiments showing copper sulfate reversing this inhibition.

This study found that LGR5 is uniquely expressed in human corneal endothelial cells and maintains endothelial cell phenotypes while inhibiting mesenchymal transformation through the Wnt pathway.

This study observed that patients with various types of hair loss had significantly lower serum zinc levels compared to healthy controls, suggesting zinc disturbance may play a role in the condition.

This study found that finasteride significantly reduced serum dihydrotestosterone levels, confirming its efficacy as a 5a-reductase inhibitor, while Permixon showed no effect in healthy male volunteers.

This review discusses the use of mushrooms and their bioactive compounds in cosmeceuticals and nutricosmetics and reports no new clinical findings, highlighting potential areas for future research and development.

Cornification evolved from keratinization in vertebrates, with differences between mammals and sauropsids.
