This study demonstrated that engineered skin substitutes using human keratinocytes and murine dermal papilla cells can develop pigmented hairs without sebaceous glands, suggesting separate pathways for hair development and eruption.

This study revealed that deficiency in the enzyme FA2H in mice affected sebaceous gland function, altered sebum composition, and caused cycling alopecia, highlighting FA2H's role in hair follicle homeostasis.

This study found that using a 900-MHz GSM mobile phone for 15 or 30 minutes significantly increased single-strand DNA breaks in human hair root cells near the phone.

This study found that neutral liposomes were most effective at delivering minoxidil into pilosebaceous units compared to other tested formulations.

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.

This study confirmed that the novel solid lipid microparticle formulation of adapalene demonstrated follicular penetration potential and targeted particle erosion in sebum in in vitro tests.

This study found that in mice lacking EGFR, elevated Wnt signaling disrupts hair follicle development by affecting cell proliferation and differentiation, revealing a critical role for EGFR in regulating these processes.

This paper reports on the structural characteristics of α-type filaments in the inner root sheath cells of guinea pig hair follicles without presenting new clinical findings.

This study investigated the role of NLRP3 inflammasomes in alopecia areata and found that outer root sheath cells may contribute to inflammation by increasing IL-1β and HMGB1 secretion when stimulated with double-stranded RNA.

In this study, researchers observed that a noncanonical mechanism involving the γ-secretase-dependent, RBPj-independent Notch intracellular domain improves survival in Msx2-Cre mice by delaying hair follicle destruction and reducing disease severity.

This study found that Hex gene expression patterns in chick embryo dorsal skin during feather bud development suggest a significant role in initiating feather morphogenesis.

This study analyzes the fine structure and protein distribution in monotreme hairs, finding similarities with other mammals and detailing unique immunocytochemical features in their inner root sheaths.

This study reports that hair analysis could potentially monitor metformin use in diabetic patients, suggesting a possible correlation between daily dose and concentration in dark hair but not in light hair.

This study found significant changes in gene and protein expression related to hair follicle development in Rex rabbits' skin during the first 8 weeks of life.

This study found that phyto-vesicles of ß-sitosterol showed better absorption and improved activity for treating androgenetic alopecia in rats compared to the compound and its complex.

This study found that inhibiting the TRPV3 channel may significantly promote hair growth and suggests a potential therapeutic approach for hair loss and related skin diseases.

This study found that postmortem root banding in hair is likely due to the degradation of the intermacrofibrillar matrix in the cortex, with no damage to the cuticle observed.

This study found that Polygonum multiflorum and Panax japonicum extracts could promote hair regrowth in mice, suggesting potential use as hair tonics.

This study found that applying HHORSC exosomes may enhance the hair inductivity of dermal papilla cells, potentially improving treatments for hair loss.

In this study, researchers found that UV radiation causes hydroxy radicals to form cuticle holes specifically between the cuticle layers in wet hair, unlike random holes caused by Fenton's reaction.

This study demonstrates that α-parvin is crucial for epidermal morphogenesis and hair follicle development by mediating integrin-dependent adhesion and actin organization in keratinocytes.

In this study, applying G. glabra root extract to female rats resulted in faster and more extensive hair growth than minoxidil or a control treatment.

This study suggests that an in ovo injection of CHIR-99021 promoted feather growth and follicle development in goose embryos by activating the Wnt signaling pathway.

This study found that finasteride-loaded microspheres effectively treated androgenic alopecia in a mouse model, showing similar hair growth effects to orally-administered finasteride.

This study found that nestin-negative hair follicle stem cells can differentiate into neural stem cell-like cells, but not mature neurons, through a multi-step neuro-induction process.

This study found that activin B promotes the initiation and development of hair follicles in both cultured and neonatal mouse skin models.

In this study, collagen I decellularized scaffolds enhanced the growth and melanotic properties of hair follicle melanocytes, suggesting their potential as effective carriers for transplantation in vitiligo treatment.

In this study, 5α-reductase inhibitors were found to have no significant impact on preventing tumorigenesis or progression in in vitro models of urothelial cancer.

In this study, researchers reported that adenosine stimulated hair shaft elongation in cultured human hair follicles by promoting proliferation and prolonging the anagen phase, suggesting the A2B adenosine receptor in outer root sheath keratinocytes as a promising target for treating hair growth disorders like alopecia.

In this study, researchers developed a method called the Stiffness-Angle Law and found that hair treated with caffeine-infused shampoo showed a 13.2% increase in stiffness, as measured by their novel evaluation technique.
