This case report describes a six-year-old child with congenital biotinidase deficiency whose symptoms, including breathlessness, alopecia, and hearing loss, were reversed with biotin supplementation.

This study reviews the potential of stem cell-based therapies, including transplants and exosome treatments, to reactivate hair follicle stem cells and promote hair growth in individuals experiencing pattern hair loss.

This study found that inhibiting the Mitochondrial Pyruvate Carrier in human scalp hair follicles caused metabolic stress that halted cell proliferation and disrupted key signaling pathways, with these effects partially reversed by an integrated stress response inhibitor.

In this study, researchers discovered that the MafB gene, which is important for macrophage differentiation, shows high expression in the pancreas and is influenced by sex steroids, with varied expression patterns in hamster tissues and during reproductive phases.

This study reports that hair samples can be used to track chronic hormone levels, revealing stress, reproductive, and sodium regulation patterns in wildebeest related to environmental factors.

This study found that severe zinc deficiency induced in weanling rats led to growth retardation, hair issues, and dermal lesions, all of which were completely reversed by zinc supplementation.

Testosterone was found to inhibit hair follicle epithelial cell proliferation in adult stumptailed macaques only when dermal papilla cells from bald scalps were present, and this effect was reversed by the antiandrogen RU 58841.

This study suggests that skin sections from 4-week-old C3H mice could serve as an in vitro model for human androgenic alopecia, as minoxidil partially reverses suppressed hair follicle elongation.

This study found that ILK deficiency disrupts hair follicle development by impairing cell polarity and laminin-511 assembly, but these defects can be partially reversed with exogenous laminin-511.

This study reviewed and categorized dermatological drugs for pregnancy and lactation according to new FDA labeling guidelines, which replaced simplistic letter categories with detailed information, aiming to improve prescribing decisions by addressing both maternal and paternal reproductive potential.

This study developed and validated a label-free assay using LC-MS to screen for S5αR inhibitors, identifying Thai herbal extracts, Impatiens balsamina L. and Curcuma longa L., as promising sources.

This study provides a framework for understanding different types of alopecias based on immune privilege collapse at specific follicular sites, revealing distinct patterns in immune effector programs and stromal influences depending on the alopecia type.

This study developed finite element models to examine skin's biomechanical properties, finding that structural heterogeneities like Rete ridges and hair follicles create distinct stress and strain patterns that may influence mechanosensation and skin integrity.

This narrative review analyzed the literature on premature hair graying, identifying potential contributors such as nutrient deficiencies, oxidative and emotional stress, smoking, genetic factors, autoimmune diseases, and medication side effects, but reported no effective treatment to reverse it, underscoring the necessity for further research.

This study observed that simvastatin promoted hair regrowth in a mouse model of alopecia areata by reducing inflammatory markers and T cell proliferation, partly through disruption of isoprenoid metabolite production.

This study found that mutations in the FGF5 gene are the primary genetic factor causing long hair in domestic cats through an autosomal recessive mechanism.

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

This study in mice found that topical pumpkin seed oil promoted hair growth and could be a promising alternative treatment for male pattern alopecia.

This study documented an increased health care burden due to post-COVID conditions in the 6 months following the acute phase of infection, providing vital evidence for resource planning.

This study found that menopausal status and hormone therapy significantly affect the histology and gene expression of the introitus, with post-menopausal women showing notable tissue remodeling associated with vaginal atrophy.

This study found that spironolactone reduced fish fecundity and caused masculinization of females at certain concentrations, while having no effect on Daphnia magna reproduction, underscoring concerns for environmental exposure to vertebrates.

This study suggests that inaudible sound at 30 kHz may promote hair growth and inhibit hair loss signals in human dermal papilla cells, indicating potential as a new treatment for androgenic alopecia.

This study found that specific junctional proteins are significantly downregulated in balding regions of the scalp in men with androgenetic alopecia, suggesting disrupted cell communication may play a role in hair loss.

Finasteride and minoxidil are effective for hair loss, with potential side effects, and JAK inhibitors show promise for alopecia areata.

This review discusses advances in protecting against chemotherapy-induced alopecia and reports no new clinical results; calcitriol and cyclosporine A emerged as promising agents in animal models with broader efficacy across multiple chemotherapy drugs.

This review discusses factors affecting hair aging and the current pharmacological treatments for androgenetic alopecia, mentioning topical minoxidil and oral finasteride, but does not present new clinical findings.

In this study, minoxidil significantly downregulated interleukin-1 alpha expression in human keratinocyte cells, suggesting an anti-inflammatory effect that may be a mechanism of action in treating alopecia.

This review discusses treatments for female sexual dysfunction in postmenopausal women, noting that the effectiveness of current pharmaceutical options is inconclusive and emphasizing the importance of individualized care.

This study found that patients with androgenetic alopecia had significantly higher COVID-19 severity compared to matched controls, suggesting a potential link between androgen pathways and disease severity. The authors suggest further research to validate this hypothesis and explore antiandrogen treatments for managing COVID-19 severity.

This review concluded that the efficacy of cosmeceutical hair serums for addressing hair loss lies in their use of bioactive peptides and plant compounds, like flavonoids and sterols, that target eight key contributing factors identified in hair loss conditions.
