In this study, researchers observed a rare presentation of alopecia areata characterized by hair shafts with segmental heterochromia and changes in thickness, indicating a fluctuating low-level inflammatory process with recovery periods in the hair's normal characteristics.

In this preliminary study, HBOT appeared to improve subjective measures of hair and scalp health in healthy adults, but objective changes in follicle density and hair properties were not statistically significant.

This study found that treatment with ritlecitinib or brepocitinib was effective in improving scalp hair loss for patients with alopecia areata over 24 weeks compared to placebo.

This study found that adult mouse dermis can be reprogrammed by epidermal cues to resemble neonatal dermis, with changes in fibroblast proliferation and extracellular matrix composition.

This study found that premature hair loss due to stress does not occur in NK-1 receptor knockout or mast cell deficient mice, suggesting a key role for neurokinin substance P and mast cell interaction in stress-related hair follicle changes.

This study developed a follicular automaton model that simulates human hair cycle dynamics and can replicate hair pattern changes associated with diffuse or androgenetic alopecia.

In this study, mice exposed to prolonged space conditions demonstrated skin atrophy, altered hair follicle cycles, and significant changes in the gene expression associated with skin muscle health.

The study found that exposing Arbas Cashmere goats to a short photoperiod significantly increased cashmere production by extending the anagen phase of hair follicles, with gene expression changes identified as contributing factors.

This study suggests that Houttuynia cordata extract may promote hair growth by stimulating dermal papilla cell proliferation and extending the anagen phase through enhanced energy metabolism and gene expression changes.

This study observed that long COVID symptoms differed between patients infected in the Delta and Omicron periods, with those in the Omicron period experiencing milder illnesses but more fatigue, insomnia, and cough.

This study observed that the OCIAD2 and DCN genes in Liaoning cashmere goats have opposite effects on hair growth by interacting with the TGF-β signaling pathway, influencing follicle morphogenesis and periodic changes.

In this study, bromocriptine's inhibition of prolactin promoted secondary follicle development during anagen in cashmere goats, likely via changes in specific gene expressions, despite not affecting fiber characteristics or primary follicle activity.

This study suggests that gamma-ray irradiation affects hair follicle density, structure, and pigmentation in mice, with some changes observed in later hair cycles.

In this study, the researchers observed that inducing and then withdrawing β-catenin expression in a bigenic mouse model caused reversible changes in skin morphology, indicating dependence on β-catenin signaling.

This study suggests that the synthetic peptide SPIKENET (SPK) may protect against long-term skin alterations in mice following coronavirus infection, offering potential therapeutic intervention for similar effects in humans post-COVID-19.

Some medications for inflammation can cause a condition with scalp rashes and hair loss, often linked to Crohn's disease, and may require treatment changes to prevent permanent hair loss.

This study suggests that edelweiss extract may promote hair growth and reduce shedding in ex vivo experiments by affecting hair follicle anagen phase duration and keratinocyte proliferation.

This study found that 3D imaging may serve as a promising tool for objectively evaluating facial vitiligo repigmentation after treatment with upadacitinib.

This integrative review developed a Spiral Model to better represent human hair follicle dynamics and aging, which may assist in distinguishing natural aging from pathological changes and improving trichological interventions.

In this study, telogen effluvium, a common form of hair loss linked to changes in the hair cycle, is examined with a focus on diagnostic methods and effective treatment options, noting that 34.2% of patients experience trichodynia.

In this study of dogs with mucocutaneous lesions caused by various dermatological conditions, the researchers observed notable changes in haemato-biochemical parameters and trichographic features, including anaemia, elevated platelet counts, and significant telogen phase hair involvement.

This article discusses disruptions in hair cycle dynamics and follicular miniaturization associated with patterned hair loss, emphasizing androgen-related changes, and reports no clinical findings.

This study found that in androgenetic alopecia patients, there is enhanced expression of type 2 TGF-β and type II receptors in hair follicles, suggesting a link to hair growth cycle changes.

In this study, patients with systemic lupus erythematosus and generalized non-scarring alopecia exhibited hair loss similar to telogen effluvium, with significant changes observed in the cuticle of telogen hairs.

This study found that epidermal-specific deletion of aPKCλ in mice disrupted hair follicle stem cell quiescence and regeneration, leading to abnormal hair cycling and skin changes.

This study found that VEGF expression and microvessel density in hair follicles of Liaoning cashmere goats follow a bimodal pattern correlated with hair development throughout the year.

This study observed that hair follicle mesenchyme in mice exhibits significant plasticity during the hair cycle, with cell migration and changes in papilla size impacting hair production.

This article discusses skin changes during pregnancy and emphasizes the importance of recognizing these physiological manifestations to prevent unnecessary tests and stress for pregnant patients; it reports no new study findings.

This study demonstrated that troxerutin may protect human dermal papilla cells from H2O2-induced damage and suggests potential in treating alopecia by inhibiting ROS-mediated cellular damage.

This study suggests that Eclipta prostrata may promote hair growth in mice and human dermal papilla cells through regulating FGF-7 and mTOR signaling.
