This study suggests that canonical BMP signaling, particularly involving Smad1 and Smad5, plays a critical role in hair follicle stem cell regulation and hair morphogenesis, with distinct roles from pSmad8.

This study found that conditioned medium from keratinocytes improved the hair-inductive properties of cultured dermal papilla cells, suggesting potential for enhancing hair follicle regeneration.

This study provides evidence that Cyclosporine A inhibits catagen development in human hair follicles, suggesting different underlying mechanisms from those observed in rodent studies.

This article discusses the presentation of chemotherapy-induced anagen effluvium as either diffuse or patterned hair loss and reports no new clinical findings.

This study demonstrated that thyroid hormone receptors play a crucial role in hair growth and skin health, as mice lacking these receptors showed impaired hair cycling and wound healing.

This study found that Akt2 and SGK3 are crucial for postnatal hair follicle development in mice, as their combined absence led to severe hair growth defects due to disrupted β-catenin-dependent transcriptional processes.

This review explores recent insights into how intrinsic gene oscillations and molecular interactions in hair follicle stem cells contribute to their regenerative potential, with potential implications for regenerative medicine, but reports no new clinical results.

This study found that the season of the year does not significantly affect the hair regrowth rate or the telogen: anagen ratio in indoor-housed Labrador retrievers.

This study identified three symptom trajectory groups in individuals with PMDD, highlighting variations in symptom severity and duration across the luteal and follicular phases.

This study successfully developed and characterized a monospecific monoclonal antibody, LHTric-1, that specifically localizes to the pre-cortical region of the hair follicle and can aid research on hair and nail formation.

This study analyzed gene expression changes during the autumn coat color change in mountain hares and found conserved gene regulation with snowshoe hares, highlighting its role in seasonal camouflage adaptation.

This study found that osteopontin mRNA is abundantly expressed in dermal papilla cells during the catagen phase of hair growth in rats, suggesting a role in this phase.

This study found that deleting podoplanin in mouse keratinocytes promoted hair follicle growth during regeneration, suggesting it may regulate hair cycling pathways that could aid in treating hair loss conditions.

This review discusses the histologic features of nonscarring alopecia and highlights the importance of clinical-pathological correlation for accurate diagnosis, but reports no new clinical results.

In this study, researchers found that interaction between transcription factor EBF1 and gene WNT10A, influenced by a genetic variant, may play a role in hair shaft formation and anagen shortening in male pattern baldness.

This review examines the role of follicular unit transplantation in restoring eyebrow fullness and architecture but does not present new experimental findings, emphasizing the importance of technique for achieving natural results.

This study observed that primary hair follicles in Liaoning Cashmere goats had broader hair bulb widths compared to secondary follicles, with the difference diminishing during the anagen phase of hair follicle development.

This study identified FP-1 as a highly specific extracellular matrix protein in follicular papilla cells, which may play a role in hair growth regulation during specific hair cycle phases.

This study found that IPL hair reduction led to significant decreases in hair count and thickness by promoting hair follicle miniaturization, increased telogen phase, and reduced cell proliferation.

In this study, researchers found that cyclophosphamide treatment unexpectedly reduced splenic melanin deposition in a murine model, whereas this effect was down-regulated more by the normal and dystrophic catagen phase of the hair cycle.

The researchers reported that Gambogic Amide may prevent hair greying and promote hair growth by maintaining follicle pigmentation in vitro through activation and migration of melanocytes.

This study suggests that TGF-alpha may function in an autocrine or juxtacrine manner rather than promoting cell proliferation during hair growth cycles in ferrets and sheep.

This case report describes a patient with eosinophilia-myalgia syndrome who experienced severe, persistent telogen effluvium.

This case report details a 3-year-old girl with short anagen syndrome, characterized by short, sparse hair, where X-ray microanalysis showed her hair's main bioelements were normal.

This study reveals that stem cell descendants in mouse hair follicles can return to their niche to retain stemness and function as primary stem cells for future hair cycles.

This article reviews various drugs reported to cause alopecia, including cytostatics and anticoagulants, but does not present new research results; it suggests that drug-related hair loss can be difficult to prove.

This study found that hair follicles across mouse skin form a heterogeneous regenerative field, with distinct cycling dynamics influenced by the balance of activator and inhibitor signals, which could inform other organ regeneration research.

This study found that topical curcumin can initiate hair growth in mice by acting as a JAK inhibitor but could not fully reverse alopecia areata, likely due to insufficient penetration to deeper skin layers.

Minoxidil helps hair grow, especially in people with mild hair loss.

Certain dietary supplements can improve hair health.
