In this study, researchers linked SARS-CoV-2 infection to telogen effluvium in some COVID-19 patients by observing the accumulation of viral proteins in hair follicle cells, which may trigger stress responses and cell death, suggesting hair follicles as a potential target in COVID-19.

In this research, the author hypothesizes that curly hair is influenced by the contraction of the Arrector Pili muscle, suggesting that its relaxation through specific treatments could potentially modulate hair follicle curvature, but further studies are needed to confirm this mechanism.

This study hypothesizes that the curling of hair may result from the contraction of the Arrector Pili Muscle, contributing to the diverse types of curly hair.

This study hypothesizes that curly hair is shaped by the contraction of the Arrector Pili Muscle within the follicle, potentially modifiable through muscle-relaxing treatments, but further research is needed to confirm this mechanism.

This review examines the roles of adenosine and caffeine in regulating hair growth cycles but reports no new results, highlighting unanswered questions about their specific mechanisms.

This study observed that outer and inner root sheaths of human hair follicles are predominantly characterized by different glycoconjugates, suggesting a relationship between specific lectin labeling and follicle differentiation.

This study suggests that inaudible sound at 30 kHz may promote hair growth and inhibit hair loss signals in human dermal papilla cells, indicating potential as a new treatment for androgenic alopecia.

This study found that keratin 15 expression is downregulated in hyperproliferative conditions like psoriasis and hypertrophic scars, suggesting it is not compatible with keratinocyte activation.

In this study, miR-31 was found to play a significant role in hair cycle regulation in mice by controlling key gene expressions involved in hair growth and differentiation.

This study found that human peptidylarginine deiminase type III is the predominant isoform in hair follicles and may modulate structural proteins during hair and hair follicle formation.

This study found that the zinc transporter ZIP10 is crucial for epidermal development, as it influences the activity of p63, promoting epidermal morphogenesis.

This study found a significant association between reduced FGF13 levels and X-linked congenital generalized hypertrichosis, suggesting FGF13's potential role in hair follicle growth and the hair cycle.

This study found that overexpression of sPLA2-X in mice was associated with alopecia and hair follicle abnormalities, highlighting its potential role in hair follicle homeostasis.

This review discusses the changes in hair follicles with aging, particularly graying due to decreased melanocyte activity, and suggests potential for hair repigmentation under certain conditions, but reports no new results.

This research found that activating a KrasG12D mutation in mice led to skin thickening, papillomas, and hair growth issues, suggesting that even rare KRAS mutations can mimic human RAS/MAPK syndrome symptoms.

In this study, researchers demonstrated that follicular tight junctions in porcine skin form a barrier to nanoparticle penetration, particularly in upper regions, which supports its use as a model for human skin.

This study suggests that PDGFA and BMP2 play a role in the hair follicle cycle in cashmere goats, with PDGFA particularly involved in activating the growth phase.

This study demonstrates the potential of infrared spectral imaging to assess hair follicle structures and heparan sulfate proteoglycan distribution across different phases of the hair growth cycle, offering promise for alopecia research.

In this study, researchers found that the matriptase-HGF-c-MET pathway may be activated in proliferative cells of human hair follicles and sebaceous glands, suggesting a potential role in hair growth regulation.

This study found that elevated beta-hydroxybutyrate levels may worsen the inflammatory immune response in alopecia areata patients and could indicate a poor prognosis with chronic hair loss.

This article reviews in-vitro and cell-free methods for assessing the efficacy of herbal ingredients in cosmetic formulations for skin health and hair growth, but it reports no new clinical results.

This study found that the MD-3 antibody significantly improved the survival of hair follicle allografts in nonhuman primates by reducing T-cell infiltration.

In this study, kartogenin promoted hair growth by enhancing cell proliferation and migration in vitro and extended hair length in mice, suggesting its potential as a treatment for hair loss.

In this review, researchers reported that pyroptosis, a type of inflammatory cell death linked to inflammasome activity, is a key factor in the pathogenesis of alopecia areata and may present new therapeutic opportunities, though most treatments are still in early research stages.

This study identified key proteins, FKBP10 and FBN2, that promote the growth cycle of secondary hair follicles in cashmere goats, with higher expression in the anagen phase, offering insights into mechanisms potentially enhancing cashmere yield and quality.

This study found that GPC1 is a key regulator of angiogenesis in hair follicles and may be an interesting target for addressing alopecia in dermatology research.

This study found that GPC1 is a key regulator of angiogenesis in human dermal microvascular endothelial cells, influenced by factors secreted by keratinocytes, and may be a target for alopecia treatment research.

This study found that GPC1 plays a crucial role in regulating angiogenesis in human dermal microvascular endothelial cells, which may make it a potential target in alopecia treatment research.

This study found that GPC1 is a significant regulator of angiogenesis in human dermal microvascular endothelial cells, suggesting its potential as a target for alopecia research.

This study observed two cases of pigmented epithelioid melanocytoma suggesting potential differing origins: one from a hair follicle's outer root sheath and another from an intradermal nevus.
