Stress can cause hair loss by negatively affecting hair follicles and this effect might be reversed with specific treatments.

Blocking prolactin increases the activity of secondary hair follicles in cashmere goats.

COX2 and ATP synthase control the size of hedgehog spines.

Blue light promotes hair growth by interacting with specific receptors in hair follicles.

FGF5s can block the effects of FGF5, which may help control hair growth in cashmere goats.

PBX1 helps reduce aging and cell death in hair follicle stem cells by decreasing DNA damage, not by improving DNA repair.

Hair follicle stem cells change states with age, affecting hair growth and aging.

Valproic acid and rapamycin protect hair follicle stem cells from damage by activating a protective pathway.

The scalp's microorganisms significantly affect hair health and disease.

Hair loss in males involves inflammation, collagen buildup, and follicle damage, with severity increasing with age and baldness duration.

Overactivating Hedgehog signaling makes hair follicle cells in mice grow hair faster and create more follicles.

Increasing PBX1 reduces aging and cell death in hair follicle stem cells by boosting SIRT1 and lowering PARP1 activity.

UV exposure causes hair thinning, graying, and changes in hair growth cycles in mice.

Exosomes from dermal papilla cells help hair follicle stem cells grow and survive.

A protein called desmoglein 3 is important for keeping hair follicle stem cells inactive and helps in their regeneration.

Hair loss caused by longer latent hair cycle and sudden miniaturization, not gradual follicle size reduction.

Dendrobium officinale polysaccharide helps hair growth by activating the WNT signaling pathway.

TLR2 helps control hair growth and regeneration, and its reduction with age or obesity can impair hair growth.

Exosomes from skin cells can boost hair growth by stimulating a gene called LEF1.

Improving dermal papilla cells can help regenerate hair follicles.

Hair loss caused by longer latent hair cycle and sudden miniaturization, not gradual follicle size reduction.

TGF-β2 helps activate hair follicle stem cells by counteracting BMP signals.

Vitamin D Receptor is crucial for normal skin and hair growth.

Different types of stem cells in hair follicles play unique roles in wound healing and hair growth, with some stem cells not originating from existing hair follicles but from non-hair follicle cells. WNT signaling and the Lhx2 factor are key in creating new hair follicles.

A reliable system was developed to distinguish hair growth stages, aiding in identifying hair growth promoters or inhibitors.

Hair follicle melanocytes die during hair regression.

Hair grows faster in the morning and is more vulnerable to damage from radiation due to the internal clock in hair follicle cells.

Mice without the vitamin D receptor gene lose hair due to disrupted hair follicle cycles.

Lichen Planopilaris and Frontal Fibrosing Alopecia may help us understand hair follicle stem cell disorders and suggest new treatments.
