Tiny particles called extracellular vesicles show potential for improving skin health in cosmetics, but more research is needed to confirm their safety and effectiveness.

Sunlight exposure damages hair follicles, but certain stem cell-derived particles can reduce this damage and help with hair regeneration.

The gel with icariin speeds up wound healing, reduces scarring, and helps hair growth by controlling BMP4 signaling. It also reduces inflammation and improves wound quality in mice, adapts to different wound shapes, and gradually releases icariin to aid healing. It also prevents too much collagen and myofibroblast formation during skin healing.

Mesenchymal stem cells show potential for skin healing and anti-aging, but more research is needed for safe use, especially regarding stem cells from induced pluripotent sources.

Dermal papilla cells can help regrow hair and are promising for hair loss treatments.

Hormones affect skin aging and fat distribution, and treatments can help, but only minoxidil is proven for female hair loss.

Chick embryo extract helps rat hair follicle stem cells potentially turn into Schwann cells, important for the nervous system.

The study concluded that similar pathways regulate hair growth in dogs and mice, and these pathways are disrupted in dogs with Alopecia X, affecting stem cells and hormone metabolism.

DHT reduces a cell's ability to promote hair growth, while 3D culture without DHT improves it.

Researchers found a new genetic mutation linked to a hair condition in a Japanese boy.

The endocannabinoid system affects oil production and inflammation in skin cells.

Skin-derived stem cells grow faster and are easier to obtain than hair follicle stem cells, but both can become various cell types.

TLR4 is important in aging-related diseases and could be a new treatment target.

Hair aging is caused by stress, hormones, inflammation, and DNA damage affecting hair growth and color.

Melatonin, a hormone, can help protect skin from aging by reducing stress, inflammation, and damage, and may also help treat hair loss in women.

Cells from the lower part of hair follicles are a promising, less invasive option for immune system therapies.

Some hair loss and prostate drugs might increase the risk of diabetes and heart disease.

Rats can't grow new hair follicles after skin wounds, unlike mice, due to differences in gene expression and response to WNT signaling.

Skin cell-derived vesicles can help heal skin injuries effectively.

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.

Insulin resistance may contribute to various skin diseases and treating it could improve skin health and prevent more serious conditions.

Eating high-glycemic and dairy foods can increase hormones that may cause acne and other health issues.

Stress hormone corticosterone blocks a growth factor to slow down hair stem cell activity and hair growth.

Zinc deficiency disrupts hair growth and cycle, but zinc supplements can fix this.

Platelet-rich plasma might help with skin aging, ulcers, and hair loss, but more research is needed to prove its effectiveness and safety.

Human skin acts like a hormone-producing organ, making and managing various hormones important for skin and hair health.

ICG-enhanced NIR laser therapy may be a promising acne treatment with improvement and no side effects.

Hormones are crucial for regulating body functions and imbalances can lead to health issues.
