This study found that an oral testosterone formulation normalized serum testosterone levels and significantly reduced SHBG in men with experimentally induced hypogonadism after nine days of treatment, suggesting potential efficacy for testosterone deficiency.

This study suggests that minoxidil may enhance hair growth by stimulating adipose-derived stem cell motility and growth factor secretion, promoting dermal papilla cell proliferation and accelerating anagen induction.

This study found that patients taking hydroxychloroquine had a significantly higher likelihood of indeterminate QuantiFERON-TB Gold test results compared to those not on the medication, independent of other immunosuppressive drug use.

This study assessed Ageratum conyzoides gel's efficacy in reducing hair loss and improving quality of life in adults with pattern baldness, finding that it decreased temporal recession and improved hair-related distress scores, with a significant reduction in 5α-reductase expression and PGD2 release in vitro.

This study suggests that vitamin A may inhibit hair follicle stem cells during refractory telogen in a dose-dependent manner, based on retinyl ester levels and vitamin A metabolism protein localization in mice.

This review discusses telogen effluvium, including its triggers, clinical presentations, and management options, and does not report new research findings, emphasizing the need for identification and exclusion of underlying causes.

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.

The authors concluded that dermal white adipose tissue, influenced by factors like light irradiation, plays a significant role in modulating hair follicle cycles and could be targeted for hair growth treatments.

This study found that stress hormones, particularly CRF, can inhibit hair growth and induce hair loss by affecting human dermal papilla cells and hair follicles, suggesting a functional HPA axis in these cells.

This study found that the prevalence of the exogen phase was negligible in women with androgenetic alopecia and telogen effluvium, with exogen accounting for a small percentage of hair in both conditions.

Targeted testing for telogen effluvium patients can save healthcare costs.

This chapter reviews various antiandrogens and androgen inhibitors, detailing their mechanisms, uses, and side effects, with a focus on spironolactone, finasteride, dutasteride, and oral contraceptives.

This essay discusses telogen effluvium, the issues surrounding its diagnosis and differentiation from other forms of hair loss, and emphasizes the need for empathetic patient care; it reports no new clinical findings.

This study found that serum ischemia-modified albumin levels were significantly higher in patients with telogen effluvium compared to healthy controls, suggesting a potential role of oxidative stress in the condition's pathogenesis.

This review discusses telogen effluvium, emphasizing its identifiable causes and treatment options, and reports no new clinical results.

This article discusses the presentation of chemotherapy-induced anagen effluvium as either diffuse or patterned hair loss and reports no new clinical findings.

This study found a significant association between low serum ferritin levels and nonscarring alopecia in women, suggesting the importance of addressing iron deficiency for treatment effectiveness.

This study found that intradermal adipocyte lineage cells in mice are necessary and sufficient to activate follicular stem cells, highlighting their role in regulating skin stem cell activity.

This article discusses the structure of hair follicles and their significance in evaluating hair disorders, but it does not report any new research findings.

This article reviews various causes of diffuse hair loss, highlighting the importance of identifying triggers through thorough examination for effective treatment and emphasizing patient education in management; it reports no new clinical findings.

This article discusses the history taking and clinical examination process for diagnosing alopecia and outlines a diagnostic approach, noting that it reports no new clinical results.

This review discusses recent advances in trichoscopy for differentiating types of alopecia and presents a systematic approach for using its diagnostic findings, but reports no new clinical results.

This review suggests that isotretinoin's effects on severe acne and various cancers may result from apoptosis, which might also explain its adverse effects through genetic variability.

This review explores the complex relationship between thyroid hormones and skin, discussing potential mechanisms and known interactions but reports no new clinical results, emphasizing the need for further research.

This article reviews the historical development of understanding the hair growth cycle, particularly anagen, catagen, and telogen phases, and reports no new clinical findings.

This review suggests that decreased serum 25-hydroxyvitamin D levels may play a role in different types of non-scarring alopecia, but further studies are needed to explore vitamin D supplementation as a therapeutic option.

This review discusses the use of topical minoxidil for various types of alopecia and reports mixed evidence on its efficacy, with stronger support noted for conditions like eyebrow hypotrichosis and chemotherapy-induced alopecia.

Quarantine stress likely worsened hair loss in women, but video consultations helped manage their condition and reduce anxiety.

This study reported that oleic acid-based nanovesicles improve follicular delivery and reduce side effects of minoxidil compared to traditional MXD lotions.
