This study investigated the effect of Astragalus membranaceus extract on hair regrowth in C57BL/6 mice with natural hair loss in the telogen phase, but specific results are not provided in the abstract.
September 2017 in “Journal of Investigative Dermatology” This study found that dermal papilla cells exhibit stage-dependent variation in histone methylation during the hair follicle cycle and display distinct chromatin marker expression when transitioning to in vitro culture.
September 2017 in “The journal of investigative dermatology/Journal of investigative dermatology” This study suggests that the outer root sheath of human hair follicles may act as a "metabolic center," capable of synthesizing glucose from lactate, which supports glycogen metabolism.
April 2017 in “Journal of Investigative Dermatology” This study found that knocking out STAT5 expression in specific mouse hair follicles after tamoxifen treatment initiated uniform hair growth, highlighting STAT5's role in regulating the hair growth cycle.
April 2016 in “Plastic and reconstructive surgery. Global open” This article lists online educational resources from the American Society of Plastic Surgeons but reports no new research findings.
November 2015 in “Chemical & engineering news” This study reported that topical drugs regrew hair in mice.
January 2015 in “OhioLink ETD Center (Ohio Library and Information Network)” This animal study found that high dietary vitamin A levels altered hair cycling by affecting WNT and BMP signaling pathways in mice, which could be reversed by reducing vitamin A intake.
This study found that basal cell carcinoma exhibits patterns of hair follicle differentiation but is stuck in telogen arrest, which can be rescued by adding noggin and TGF-β2 in vitro.
March 2014 in “Journal of The American Academy of Dermatology” Mycophenolic acid may help hair grow by activating pathways important for hair growth.
This study found that Chrysanthemum zawadskii extract may promote hair growth by inducing an earlier conversion of telogen to anagen and increasing the proliferation of dermal papilla cells in mice and human hair follicle cultures.
July 2013 in “DOAJ (DOAJ: Directory of Open Access Journals)” This article reviews the effects of minoxidil on hair growth, highlighting its ability to stimulate hair follicle proliferation, but reports no new clinical findings.
June 2013 in “Faculty Opinions – Post-Publication Peer Review of the Biomedical Literature” This study found that Wnt ligands secreted by the hair follicle epithelium are crucial for hair follicle regeneration in adults and could inform treatments for hair disorders like alopecia.
February 2013 in “Journal of the American Academy of Dermatology” This case report found that intense focused skin tightening ultrasound reduced excessive underarm sweating by nearly 80% in two patients and was associated with temporary side effects like tenderness and redness.
January 2013 in “Revista brasileira de medicina” This article discusses the clinical characteristics and treatment considerations for different types of alopecia, reporting no new research findings.
January 2013 in “Tampere University Institutional Repository (Tampere University)” This study observed that Tudor-SN protein may play a significant role in the immune system and that polyamines can influence hair growth in a mouse model.
October 2012 in “Humana Press eBooks” This article discusses the historical and current uses of grape seeds in various industries but reports no new research findings.
April 2012 in “Cancer Research” In this study, mouse models with EGFR deficiency showed that disrupted hair follicle cycling leads to increased mast cell numbers and inflammation, suggesting EGFR's role in managing hair cycle transitions and preventing folliculitis.
The researchers found that melatonin implantation in Cashmere goats influenced PDGFA gene expression and hair growth cycles, indicating it may control hair phase transformation from growth to catagen and telogen.
January 2012 in “Journal of Northwest A & F University” In this study, the researchers observed that Eda mRNA expression in goat skin peaks during the catagen phase of the hair cycle, suggesting its involvement in hair cycle regulation.
April 2010 in “PubMed Central” This abstract discusses the FDA approval of Latisse (bimatoprost) for increasing eyelash growth in patients with eyelash hypotrichosis and highlights its efficacy while noting unresolved effectiveness in certain conditions and potential side effects.
January 2007 in “한국미용학회지” This study found that a lack of fat tissues in the hair root during the telogen phase might indicate hair loss, potentially providing a standard for identifying hair conditions and the impact of cytotoxic drugs.
January 2007 in “한국미용학회지” This study observed that in the telogen phase, hair roots from people with alopecia showed reduced fat tissues compared to ordinary people, suggesting a potential morphological marker for distinguishing hair conditions.
January 2006 in “Chinese Journal of Dermatology” In this study, latanoprost at certain concentrations promoted the growth of pig hair follicles in vitro by possibly extending the anagen phase of the hair cycle.
