This study found that pelage abnormalities in Harlequin mutant mice are linked to severe AIF deficiency and associated with altered expression of genes related to hair structure.

This study showed that in C3H/HeJ mice, focal follicular inflammation starts before overt hair loss, with inflammation severity possibly reaching a threshold causing hair follicle dystrophy prior to visible hair loss.

This article reviews the cellular dynamics affecting dermal papilla size in androgenetic alopecia and suggests targeting DP size could improve therapies, but it presents no new clinical data.

In this study, anthralin treatment led to hair regrowth in alopecia areata-like affected C3H/HeJ mice, suggesting it may be an effective therapy for this condition.

This review provides guidance on using two-photon microscopy for real-time and long-term visualization of stem cell activity in live mice skin, focusing on its application in researching skin and stem cell biology.

In this study, human placenta extract was observed to enhance the hair-growth-promoting effects of minoxidil and stimulate earlier and prolonged anagen phases in a mouse model.

This commentary reviews potential dietary and mineral influences on androgenetic alopecia and suggests considering a diet low in cholesterol and glycaemic index with improved glucose control and magnesium fortification, without new clinical results.

This study found that hair follicles from dogs with recurrent flank alopecia regenerated and regrew hair when grafted onto mice, suggesting systemic rather than local factors may drive the condition.

This study identified new genetic variants on chromosome 20p11 associated with male pattern baldness.

This study found that aging mice experience slower and more fragmented hair cycle waves, but transplanting aged skin to a young host can partially restore hair cycling, implicating extracellular factors.

This study found that mice with a specific loss of DNA methyltransferase 1 showed uneven epidermal thickness, reduced hair regeneration, and progressive alopecia, emphasizing DNA methylation's role in stem cell homeostasis.

Minoxidil helps some bald men, but most lose hair again when stopping.

This study found that a genetic deletion causing truncated desmoglein 3 protein in mice led to severe pathologies, including cyclic hair loss and immunodeficiency, suggesting possible implications for human desmosome-related diseases.

This study found that mutant mice with the we/we wal/wal genotype exhibit significant defects in hair shaft structure and epidermis stratification, correlating with postnatal alopecia symptoms.

PGD2 stops hair growth and is higher in bald men with AGA.

This study indicates that Fructus panax ginseng extract may promote hair growth by increasing proliferation in human hair dermal papilla cells and lengthening the anagen phase in mice.

This study found that mechlorethamine restored hair growth in mice with alopecia-areata-like disease by eliminating infiltrated lymphocytes and inhibiting certain pro-inflammatory cytokines in treated skin areas.

This study found that exposure to 50 Hz electromagnetic fields enhanced hair regrowth in mice by increasing stem cell proliferation and keratinocyte growth factor expression, suggesting potential benefits for hair loss treatment.

In this study, DOP treatment improved hair regrowth in androgenetic alopecia by altering local steroid metabolism and follicular morphology.

This study found that dihydrotestosterone induced hair loss and changes in hair morphology in male C57BL/6 mice, effects that could be partially reversed by the AR antagonist bicalutamide.

This study suggests that skin sections from 4-week-old C3H mice could serve as an in vitro model for human androgenic alopecia, as minoxidil partially reverses suppressed hair follicle elongation.

This study observed that injecting a combination of human cultured dermal papilla and epithelial cells induced hair growth in a mouse model.

This study found that tianeptine may suppress the transition to catagen, promoting hair growth in a stress-induced alopecia areata mouse model.

In this study, researchers identified 32 differentially expressed genes involved in androgenetic alopecia, with down-regulated genes associated with Wnt and TGF-beta signaling and up-regulated genes linked to oxidative stress pathways.

This study found that Helianthus annuus oil promoted hair growth in a testosterone-induced alopecia mouse model, with higher hair density observed compared to untreated mice, though it was less effective than the standard minoxidil treatment.

In this study, researchers observed that different ERK signal activation dynamics during hair follicle regeneration are linked to cell fate specification and are affected by distinct upstream signaling pathways.

This study reported that CCT oligodeoxynucleotide induced patchy hair loss in male mice with specific genetic traits, suggesting gender and genetic preferences in immune response.

This study developed a transgenic mouse model to explore androgenetic alopecia, finding that inducible COX2 expression led to sebaceous gland changes and hair miniaturization, with reversible effects upon reducing COX2.

In this study, DHT was observed to have varying effects on hair follicle growth and related protein expression depending on concentration, with the Wnt/β-catenin pathway potentially playing a significant role.

This study found that MED1 deficiency in keratinocytes accelerates skin wound healing in young mice but delays healing in older mice, suggesting differential roles in epidermal regeneration with age.
