This study investigated multiple alkaline oxidative dehairing systems and found a consistent reaction mechanism for disulfide cleavage across systems, enhancing hair solubilization by enabling structural swelling and water uptake.

This study found that combining ablative fractional CO₂ laser therapy with hair growth factors significantly increased hair density in men with androgenetic alopecia compared to using growth factors alone.

Coconut oil can penetrate hair better than mineral oil, potentially protecting against damage.

In this mouse study, UVA and UVB exposure led to hair follicle miniaturization, graying, and prolonged hair cycle duration, associated with changes in stem cells and increased Wnt signaling activity.

This article highlights that trichorrhexis nodosa, a common type of hair breakage, is influenced by factors like heat styling and chemical treatments, with potential FDA action on formaldehyde usage in hair products potentially altering its treatment approach.

In this study, hair anomalies associated with acrodermatitis enteropathica in a young girl improved significantly after two years of zinc therapy.

This study reports an abnormal onion-shaped swelling on the hair shafts of some Abyssinian cats, affecting the appearance of their coat, though skin and hair structures appear normal under the microscope.

This article describes a case of localized trichorrhexis nodosa in a patient with otherwise normal hair, highlighting the condition's response to trauma and diagnostic process but reporting no new clinical findings.

This article reports a case of a 19-month-old boy with scalp erythematous papules and hair loss, showing no improvement with initial treatment.

Scurvy, caused by vitamin C deficiency, can occur in people with restrictive diets and can be diagnosed by twisted hair shafts.

This report describes a 3.5-year-old girl with argininosuccinicaciduria, highlighting congenital trichorrhexis nodosa as a notable feature associated with the disorder.

This study reports that structural abnormalities in the inner root sheath of hair follicles may cause the hair shaft to be loosely attached in patients with loose anagen hair syndrome.

In this case report, researchers documented a 19-year-old male professional athlete with acquired trichorrhexis nodosa, noting environmental factors like chlorine exposure during swimming may have contributed to his condition, which improved after advice on hair care changes.

Trichoscopy is a useful non-invasive method for diagnosing different hair loss conditions.

This article reviews major types of genetic hair shaft defects and associated syndromes, emphasizing understanding histologic features and diagnostic methods, but reports no new clinical findings.

This study found that two unrelated domestic shorthair cats had novel DSG4 gene mutations causing defective hair shafts, representing the first report of pathogenic DSG4 variants in domestic animals.

This study identified acute localized telogen effluvium as a histopathologic mechanism for temporal hair loss following rhytidectomy.

This study identified acute localized telogen effluvium as a potential cause of temporal hair loss following rhytidectomy.

In this study, hair damaged by permanent dye showed signs of recovery over time, with near complete restoration to its original state after eight weeks.

This study describes how shotgun proteomics can identify over 300 proteins in hair shafts, potentially allowing for the diagnosis of diseases through noninvasive human proteome sampling.

Hair transplant complications were likely due to deep graft placement and rough handling.

This article reviews hair and nail disorders in children, emphasizing their prevalence, congenital and acquired origins, and the diagnostic challenges compared to treatment, but reports no new clinical results.

This paper reviews hair structure and damage from grooming and cosmetic exposure but reports no new clinical findings; it suggests collaboration between dermatologists and cosmetic chemists to improve hair care products.

This paper reviews the literature on acquired trichorrhexis nodosa, a clinical hair loss diagnosis associated with hair care practices, particularly in those with tightly curled hair, and emphasizes management through protective hair care regimens rather than traditional prescription therapies.

This study found that keratin 17 and TNFα play interdependent roles in regulating hair follicle cycling, with TNFα required for the anagen–catagen transition and its ablation partially rescuing hair cycling defects in K17-null mice.

This study found that transcription factors HOXC13, LEF1, and FOXN1 repress DSG4 transcription, with the Notch pathway possibly involved in maintaining DSG4 expression in hair follicles.

Most hair loss in children is caused by a few common conditions, and it's important to diagnose these properly and support the child's mental health.

This review discusses the limited objective evidence for using finasteride in women with alopecia, suggesting that it could be considered for those who don't benefit from minoxidil, but reports no new clinical results.

This review explains the mechanical composition and molecular interactions that determine hair's mechanical properties, without providing any new experimental findings.

This review discusses the impact of various exogenous agents on hair, such as cosmetics and radiation, but reports no new experimental results.
