This study suggests that impaired VDR signaling in mice leads to dysregulated Ddit4 expression, impacting hair cycle progression and wound healing.

Hair transplant surgery using micropunch can cause blood vessel damage similar to vasculitis in some cases.

This review highlights recent advancements in FUE hair transplantation techniques and technologies, noting significant improvements in reducing follicle damage and increasing procedure speed, while emphasizing the need for surgeons to choose suitable devices for each patient's specific needs.

This article presents a rationale for using a combination of follicular units and slit grafts in hair transplanting and reports no new clinical results.

This study evaluated the therapeutic response of an Afro-descendant patient with non-scarring alopecia after prolonged use of alkaline straighteners and mechanical traction, highlighting the susceptibility of Afro hair to chemical and mechanical damage due to its structure.

This research reports that multilamellar phospholipid liposomes showed the highest follicular penetration of a water-soluble dye in vitro compared to other cosmetic vehicles, suggesting potential benefits for enhancing hair conditioning and treating hair loss.

This review discusses how pesticide exposure leads to hair loss and explores therapeutic options, including conventional and gene therapies, as well as herbal remedies like ginseng and green tea, which may counteract these effects by addressing the toxicological impact on hair follicles.

This study demonstrated that a new non-invasive method for collecting and analyzing mouse hair follicles could replace traditional biopsy methods, providing advantages for translational research and routine applications.

Targeting immune pathways like JAK/STAT may help treat frontal fibrosing alopecia.

In this in vitro study, red ginseng extract and its main ginsenoside, G-Rb1, were found to protect human hair follicular keratinocytes from oxidative damage, preventing apoptosis, promoting hair growth, and modulating hair cycle transitions by influencing specific cellular signaling pathways.

This study demonstrates that sebaceous gland loss is a common early feature in primary scarring alopecia and suggests that inflammation of sebaceous glands or ducts may contribute to follicular damage.

In this study, researchers observed that follicular damage and stem cell loss in frontal fibrosing alopecia may be mediated by immune attacks at the bulge region, suggesting potential for JAK/STAT-targeting treatments to prevent progression.

This letter clarifies that colchicine induces anagen hair loss, as shown in animal studies, and corrects a misquotation by Kligman, who suggested it caused telogen effluvium.

This study observed that pigmented casts are present in various alopecia types but are not specific to any single diagnosis, with distinct morphological features noted in trichotillomania.

This case study describes a 33-year-old woman with chronic myelogenous leukemia who developed nonscarring alopecia after starting nilotinib therapy, linked to perifollicular inflammation.

Up to 50% of scalp hair can be lost before it appears thin, and treatment is only needed for hair loss caused by diseases or deficiencies.

Ingrown hairs are a common feature in scarring alopecias due to follicular damage.

This study observed a rare case of alopecia areata with granulomatous inflammation, successfully treated with intralesional triamcinolone, leading to complete hair regrowth within two months, highlighting the need for careful diagnosis to distinguish it from other granulomatous alopecias.

Long-term exposure to air pollution increases the risk of hair loss.

This review examined three studies on dermaroller monotherapy for hair loss, finding inconsistent efficacy and diverse methods, with risks of follicular damage and infection noted; standardized protocols are urgently needed for safe practice.

This case report describes a 7-year-old girl who developed radiation-induced alopecia after a neurointerventional procedure, with dermoscopy revealing specific hair and scalp patterns that helped diagnose this rare complication. The findings highlight the importance of dermoscopy in distinguishing RIA from other alopecic disorders in children.

This case report describes how a 23-year-old woman experienced eyebrow thinning and hair loss linked to cosmetic use, with diagnostic tests confirming follicular damage. Discontinuing the product led to eyebrow regrowth, highlighting potential risks from cosmetics and the value of non-invasive diagnostics for evaluation.

This study reports that Hair RiseTM microemulsion, made from plant extracts, significantly enhanced hair follicle cell growth and improved hair growth signaling pathways, suggesting it as a plant-based alternative for androgenetic alopecia treatment.

This abstract discusses the classification of scarring alopecia, distinguishing it from secondary scarring alopecia and detailing its subtypes based on inflammation patterns and cells present during the disease's active phase, but reports no new clinical results.

This letter contains an apology from the author to Dr. Malkinson for remarks that were unintentionally offensive, acknowledging Dr. Malkinson's superior understanding of the discussed problem.

This study reported that albino Wistar rats exposed to chemical hair straighteners showed significant hair fiber damage and scalp skin deterioration, which worsened with repeated and prolonged application, highlighting the cytotoxic potential of these products and potential systemic risks.

This study found that deleting the miRNA processing enzymes Drosha and Dicer from mouse skin epithelial cells disrupted normal hair follicle development and maintenance, leading to follicular degradation and stem cell loss during the growth phase.

This review discusses the role of oxidative stress in hair greying and suggests that understanding melanocyte susceptibility at different follicular locations may help develop therapies for preventing and reversing the process; it reports no new experimental results.

This study found that water-filtered infrared A radiation can induce the release of a model drug from gold nanoparticle-doped particles in hair follicles in an ex vivo porcine skin model, suggesting feasibility for follicular drug delivery systems.

In this study, researchers reported that chronic UV exposure may contribute to androgenic alopecia progression by influencing hair cycle changes and exacerbating solar elastosis in the scalp.
