Apple stem cell extract may increase the number of stem cells in a part of the hair follicle.

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

The control system for hair growth cycles is not well understood and needs more research.

Human hair follicle organ culture is a useful model for hair research with potential for studying hair biology and testing treatments.

The conclusion is that understanding how hair follicle stem cells live or die is important for maintaining healthy tissue and repairing injuries, and could help treat hair loss, but there are still challenges to overcome.

The document explains hair growth and shedding, factors affecting it, and methods to evaluate hair loss, emphasizing the importance of skin biopsy for diagnosis.

Removing a specific gene in certain skin cells causes hair loss on the body by disrupting normal hair development.

The transition from growth to regression in Cashmere goat hair follicles involves changes in expression of genes related to keratin and cell differentiation.

Hair stops producing melanin as it transitions from the growth phase to the resting phase.

Mimicking growth factors in a topical solution can prolong hair growth phase and reduce hair loss without side effects.

Hair growth-related cells need the enzyme SCD1 to help maintain the area that supports hair growth.

GasderminA3 is important for normal hair cycle transitions by controlling Wnt signaling.

Brain-Derived Neurotrophic Factor (BDNF) slows down hair growth and promotes hair follicle regression.

Genes related to pigmentation, body rhythms, and behavior change during hares' seasonal coat color transition, with a common genetic mechanism in two hare species.

The document concludes that understanding hair follicle biology can lead to better hair loss treatments.

Human hair follicles switch between active and resting phases unpredictably.

Hair follicle melanocytes die during hair regression.

Edar signaling is crucial for controlling hair growth and regression.

Different hair growth problems are caused by genetic issues or changes in hair growth cycles, and new treatments are being developed.

Hair growth is influenced by hormones and goes through different phases; androgens can both promote and inhibit hair growth depending on the body area.

Researchers identified genes that may affect hair growth in Cashmere goats.

Researchers created a lab model to study human hair growth, showing it can grow and self-regulate outside the body.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

Hair loss occurs due to fewer papillary cells, smaller follicles, and shorter growth phases.

Mitochondrial dysfunction may contribute to chronic inflammation and immune system issues in Lichen planopilaris.

The conclusion is that we need more effective hair loss treatments than the current ones, and these could include new drugs, gene and stem cell therapy, hormones, and scalp cooling, but they all need thorough safety testing.

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

The conclusion is that Fgf18 and Tgf-ß signaling could be targeted for hair loss treatments.

Activating β-catenin in certain skin cells speeds up hair growth in mice.

MPA increases cancer spread by boosting Eph A2 activity.
