TNF-a may not be as involved in certain types of hair loss as previously thought.

Syphilitic alopecia is a rare hair loss condition in secondary syphilis that looks similar to another condition but can be diagnosed with specific tests and responds to antibiotics.

The document concludes that diagnosing hair loss requires evaluating multiple histological features, as no single feature is definitive on its own.

Mimicking growth factors in a topical solution can prolong hair growth phase and reduce hair loss without side effects.

This study found that integrin alpha-6 and p63 may play a role in hair loss, with variable expression patterns in different types of alopecia observed in scalp biopsy samples.

This study found that a 1% 11a-hydroxyprogesterone lotion appeared to increase hair growth parameters in male androgenetic alopecia patients compared to untreated controls.

This study found that Hopx labels a long-lived progenitor population in hair follicles, which contributes to hair follicle stem cell homeostasis and has an alternative origin from previously thought progenitors.

This study found that anagen hair follicles can quickly regenerate after radiation damage by forming new progenitor cells outside the bulge, bypassing the need for telogen entry.

This study found that a specially designed water-in-oil microemulsion containing Panax notoginseng saponins improved hair density and other hair health indicators in mice with telogen effluvium and androgenetic alopecia, offering a promising multi-mechanism strategy for alopecia treatment with potentially fewer side effects than traditional methods.

This letter to the editors discusses the nature of alopecia in Cronkhite–Canada syndrome and questions whether it is truly telogen effluvium, but it reports no new clinical findings.

This letter discusses a trichoscopic feature called the color-transition sign for differentiating between alopecia areata incognita and telogen effluvium, and reports no new clinical results.

This case study observed a massive lithium overdose in a 38-year-old woman with bipolar disorder, who survived despite extremely high lithium concentrations through continuous venovenous hemodiafiltration.

This study observed that in men with androgenetic alopecia, frontal hair regions showed reduced density, diameter, and growth rate compared to occipital regions, worsening with advanced stages.

This study describes trichilemmal keratinization as a distinct process of hair follicle keratinization that occurs in specific areas of the outer root sheath, illustrated using electron microscopy on dog hair.

In this article, researchers explore the causes, diagnostic approaches, and treatment strategies for diffuse telogen alopecia, emphasizing the importance of identifying triggers such as stress and metabolic disorders to effectively manage this hair loss condition.

This study reported that patients experiencing hair loss after Covid-19 infection, particularly women, showed significant improvement with homeopathic remedies, suggesting homoeopathy's potential role in addressing Covid-related, stress-induced hair loss where modern medicine lacks specific interventions.

This review discusses telogen effluvium, including its causes, symptoms, diagnostic methods, and treatment strategies, without presenting new clinical findings.

This study found that Morus alba root extract activates β-catenin in hair follicle dermal papilla cells, promoting the transition to the anagen phase and enhancing hair growth factor secretion.

In this study, a topical Ashwagandha serum significantly improved hair growth, density, thickness, and quality of life in adults with mild to moderate hair loss compared to a placebo, demonstrating potential as an effective and safer alternative treatment for alopecia.

This study found that Sophora flavescens extract promoted hair growth in mice by advancing the hair cycle and may inhibit acne-causing bacteria, though it did not affect in vitro hair follicle cell growth.

This review outlines a systematic method for diagnosing hair loss and presents no new findings; the authors emphasize the importance of biopsy in cicatricial alopecia cases.

This study found that basal cell carcinoma exhibits patterns of hair follicle differentiation but is stuck in telogen arrest, which can be rescued by adding noggin and TGF-β2 in vitro.

This case report describes a 37-year-old woman whose recurrent hair shedding was associated with low iron stores and a miscarriage, with improvements seen after increased iron intake.

This article discusses various types of alopecia, their causes, and potential treatments, but it provides no new clinical results or studies.

This chapter describes two simple, noninvasive methods — the pull test and modified wash test — which can diagnose and assess the severity of female hair loss, including conditions like telogen effluvium and androgenetic alopecia.

This article reviews the molecular interactions involved in hair follicle cycling and highlights the role of dermal papilla cells, but it presents no new research findings.

This article reviews the potential of stem cell-derived exosomes as a therapeutic approach for androgenic alopecia, noting their advantages over traditional cell therapy in repairing and regenerating hair follicles to address hair loss.

This letter to the editor mentions reports of hair loss potentially related to 5-aminosalicylic acid enemas, but suggests it may be due to telogen effluvium from severe inflammatory bowel disease rather than a direct effect.

This study observed that PAI-2 is consistently expressed in differentiating cells of murine hair and nail, suggesting it may function as a marker of differentiation and possibly protect against premature cell death.

This study found that low fluence photoepilation with intense pulsed light targets the pigmented area of hair follicles, causing temporary hair loss by inducing a catagen-like state without severe follicle damage.
