Scientists have improved 3D models of human skin for research and medical uses, but still face challenges in perfectly replicating real skin.

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

Melatonin, usually known for sleep regulation, also has antioxidant properties that can protect skin, stimulate hair growth, and improve skin conditions, with topical application being more effective than oral use.

Regulatory T cells help heal skin and grow hair, and their absence can lead to healing issues and hair loss.

Intense pulsed light treatment mainly damages pigmented hair parts but spares stem cells, allowing hair to regrow.

3D cell-derived matrices improve tissue regeneration and disease modeling.

A device was made in 2008 to measure hair loss severity. Other findings include: frizzy mutation in mice isn't related to Fgfr2, C/EBPx marks preadipocytes, Cyclosporin A speeds up hair growth in mice, blocking plasmin and metalloproteinases hinders healing, hyperbaric oxygen helps ischemic wound healing, amniotic membranes heal wounds better than polyurethane foam, rhVEGF165 from a fibrin matrix improves tissue flap viability and induces VEGF-R2 expression, and bFGF enhances wound healing and reduces scarring in rabbits.

A new 3D culture system helps grow and study mouse skin stem cells for a long time.

Norepinephrine helps skin cells grow, which is important for hair growth.

Thiolated cyclodextrin-based nanoparticles effectively deliver Minoxidil for scalp treatment without causing skin irritation.

Testosterone helps prevent skin damage in males by acting through both estrogen and androgen pathways.

The document concludes that understanding adult stem cells and their environments can help improve skin regeneration in the future.

Thermal spring waters and their microbes could be good for skin health and treating some skin conditions in skincare products.

Zinc pyrithione dissolves quickly on the skin and in hair follicles, especially in smaller particles.

Skin stem cells in hair follicles are important for touch sensation.

Spironolactone is used in dermatology to treat skin conditions related to hormones, but is not safe for pregnant women or men.

3D high-frequency ultrasound can help diagnose skin and hair conditions without invasive biopsies.

The P25H5-O microneedles effectively deliver substances through hair follicles and are safe for skin cells.

Rosemary and neem extract may be an effective natural treatment for dandruff and hair loss.

Hair follicle cells age faster and lose pigment due to less catalase, causing hair to turn gray.

Tcf3 helps cells move and heal wounds by controlling lipocalin 2.

Neurotrophin-4 increases calcium current in specific mouse neurons through the PI3K pathway.

Peppermint oil can effectively promote hair growth without being toxic.

Tiny natural vesicles from cells might help treat hair loss.

Glutamine metabolism affects hair stem cell maintenance and their ability to change back to stem cells.

Sphinganine can reduce hair loss and improve scalp health.

Nanotechnology shows promise for better chronic wound healing but needs more research.

Hydrogel with M2-derived exosomes improves wound healing by slowly releasing exosomes that help reduce inflammation and promote tissue repair.

Pomegranate leaf extract may help with hair growth, dandruff, and lice.

The nail matrix has a reduced immune response, protecting it from autoimmunity.
