This review discusses the nocebo effect in dermatology, highlighting its mechanisms, implications, and strategies to manage it, but does not provide new clinical research findings.

This study concluded that epidermal growth factor may induce a 'catagen-like' phase in human hair follicles by disrupting normal cellular proliferation and migration patterns.

Minoxidil helps hair growth by increasing blood flow and stimulating hair follicles.

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 study found that applying dexamethasone to mice induced catagen-like follicle changes significantly earlier and more consistently than a vehicle, such changes being useful for studying hair follicle regression.

This study found that low-output laser irradiation demonstrates biostimulatory effects on several biological systems and processes, including hair growth, wound healing, and immune function, with effects influenced by dose and exhibiting both stimulatory and inhibitory potential.

This study found that transgenic mice expressing a mutant E1a oncoprotein in their skin had disturbed hair follicle maturation but did not show increased tumor development or proliferation.

This study presents additional data suggesting that the absence of nerve endings in certain segments of human hair follicles influences the asymmetrical distribution of electrical charges, as indicated by no precipitation of Potassium Ferricyanide crystals.

Krt6a-Cre transgenic mice help study gene effects on hair follicle development and tumor suppression.

People with an imbalance between their cognitive and emotional empathy have lower levels of the hormone oxytocin in their hair.

In this study, deer hair follicles were shown to be an effective in vitro bioassay model, demonstrating that K(ATP) channel modulators directly influence hair follicle growth through specific channel types.

This study found that short-term treatment with ROCKi significantly increased keratinocyte stem cell proliferation without affecting their stemness, suggesting a potential safe approach for improving in vitro keratinocyte cultures for clinical applications.

This study found that bursts of ERK activation in the epidermis of mice were linked to cell division, supporting synchronized cell proliferation and transient ERK activity in living tissues.

This study found that infused mouse epidermal growth factor induced wool follicle involution through a quasi-physiological process similar to catagen and a separate pathological action, resulting in fleece 'break' or shedding.

Hair movement can indicate hair quality and health.

This study found that topically applied Chinese black tea extract, when fermented and combined with capsaicin, significantly promoted hair growth in mice, potentially involving estrogen receptor interactions.

This study reported that Dkk4-knockout mice showed disrupted hair follicle patterning, suggesting a WNT-DKK axis may influence regional specificities in hair follicle induction related to androgenetic alopecia.

This study found that transgenic mice expressing HPV E6/E7 in the outer root sheath experience continuous hair follicle cycling due to delayed catagen entrance and insensitivity to telogen resting signals.

In this study, researchers found that Biofield Energy Healing Treatment significantly increased the proliferation of human hair follicle dermal papilla cells in vitro, suggesting potential hair growth benefits.

In this study, researchers used the Displacement Framework to explore how hair, especially in Black communities, serves as both a biological archive and a site of social pressure, with natural hair return symbolizing a move back to genetic origins.

This study found that minoxidil sulfate stimulates Cl channels, potentially depolarization-activated and outwardly rectifying, in eccrine clear cells, while minoxidil itself stimulates Ca-insensitive K currents.

This study found that the uptake of molecules by hair is influenced by both hydrophobic and ionic charge interactions, with binding affinity decreasing as pH approaches the solute's dissociation constant.

In this study, Biofield Energy Healing significantly increased the proliferation of human hair follicle dermal papilla cells in vitro, suggesting potential as a hair growth promoter.

In this animal study, topical minoxidil shortened the telogen phase of hair growth cycles in rats, suggesting it may stimulate certain follicles to progress more rapidly to anagen.

This study found that combining electrical stimulation with minoxidil had a synergistic effect on the proliferation of cultured human dermal papilla cells, potentially through enhanced activation of the Wnt/β-catenin pathway.

In this study, the researchers reported that altering β-catenin signaling in a transgenic mouse model led to changes in skin cell fate, notably converting hair follicle cells into epidermal cells and forming cysts instead of follicles.

This study found that overexpression of erythropoietin disrupted hair growth in mice by affecting dermal fat lipogenesis and lipolysis, leading to poor hair follicle development and truncal alopecia.
