Hair growth is influenced by various body and external factors, and neighboring hairs communicate to synchronize regeneration.

Hair follicles are normally protected from the immune system, but when this protection fails, it can cause hair loss in alopecia areata.

New hair can grow from large wounds in mice, but less so as they age, involving reprogramming of skin cells and specific molecular pathways.

PRP shows promise for improving facial wrinkles, skin elasticity, and hair growth, but more research is needed to standardize its use and understand its effects.

The gene Msx2 is crucial for hair follicle regeneration during wound healing.

Melatonin directly affects mouse hair follicles and may influence hair growth.

Hair graying is influenced by factors like nerves, fat cells, and immune cells, not just hair follicles.

DNA methylation is essential for skin and hair follicle development, and could be a target for treating skin diseases.

Skin problems can be caused or worsened by physical forces and pressure on the skin.

The new microwell device helps grow more hair stem cells that can regenerate hair.

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

Gene network oscillations inside hair stem cells are key for hair growth regulation and could help treat hair loss.

Activating the GDNF-GFRα1-RET signaling pathway could potentially promote skin and limb regeneration in humans and could be used to treat hair loss and promote wound healing.

Hair disorders are caused by a complex mix of biology, genetics, hormones, and environmental factors, affecting hair growth and leading to conditions like alopecia.

Researchers developed a scaffold that releases a healing drug over time, improving wound healing and skin regeneration.

New treatments for vitiligo may focus on protecting melanocyte stem cells from stress and targeting specific pathways involved in the condition.

Scientists have made progress in creating replacement teeth, hair, and glands that work, which could lead to new treatments for missing teeth, baldness, and dryness conditions.

Targeting the actin cytoskeleton could improve skin healing and reduce scarring.

Prominin-1 expressing cells in the dermal papilla help regulate hair follicle size and communication but don't aid in skin repair.

Isoproterenol helps hair follicle stem cells turn into beating heart muscle cells.

High levels of ERK activity are key for tissue regeneration in spiny mice, and activating ERK can potentially redirect scar-forming healing towards regenerative healing in mammals.

Hair follicles help absorb and store topical compounds, aiding targeted drug delivery.

Using skin stem cells and certain molecules might lead to scar-free skin healing.

Transplanted whisker follicles caused long hair growth on the spinal cords of mice.

New treatments for hair loss show promise, including plasma, stem cells, and hair-stimulating complexes, but more research is needed to fully understand them.

The environment around melanocyte stem cells is key for hair regeneration and color, with certain injuries affecting hair color and potential treatments for pigmentation disorders.

Old hair follicles grew better when moved to a young environment.

Blocking JAK-STAT signaling can lead to hair growth.

Environmental factors at different levels control hair stem cell activity, which could lead to new hair growth and alopecia treatments.
