Hair loss and aging are caused by the breakdown of a key protein in hair stem cells.

Iron deficiency is the main cause of hair loss in women, and iron supplements started within 6 months can improve hair health.

Scientists can grow human hair follicle stem cells in a lab without changing their nature, which could help treat hair loss.

Medium-sized particles penetrate hair follicles better than smaller or larger ones, which could improve delivery of skin treatments.

Retinoic acid-binding proteins in skin are regulated by β-catenin and Notch signalling.

The vitamin D receptor is essential for skin stem cells to grow, move, and become different cell types needed for skin healing.

Regenerative cellular therapies show promise for treating non-scarring hair loss but need more research.

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.

Microneedling combined with platelet-rich plasma therapy is more effective for hair regrowth in androgenic alopecia than microneedling alone, but it's more painful.

Particles around 100 nm can penetrate and stay in hair follicles without passing through healthy skin, making them safe for use in topical products and useful for targeted drug delivery.

Hair loss in male pattern baldness involves muscle degeneration and increased scalp fat.

Transplanting hair follicles into chronic ulcers helps them heal better.

PRFM may help treat hair loss, especially in mild cases.

Injecting platelet-rich plasma during hair transplant surgery improves hair regrowth rate, speeds up skin recovery, and enhances hair quality.

Skin stem cells maintain and repair the outer layer of skin, with some types being essential for healing wounds.

SDF-1/CXCL12 and its receptor CXCR4 are crucial for melanocyte movement in mouse hair follicles.

Alopecia areata is a hair loss condition caused by immune factors and can be treated with JAK inhibitors.

New hair loss treatments may include topical medications, injections, and improved transplant methods.

Microspheres about 1.5 micrometers in size can best penetrate hair follicles, potentially reaching important stem cells.

Creating fully functional artificial skin for chronic wounds is still very challenging.

Engineered skin substitutes can grow hair but have limitations like missing sebaceous glands and hair not breaking through the skin naturally.

Treg cell-based therapies might help treat hair loss from alopecia areata, but more research is needed to confirm safety and effectiveness.

Wnt signaling is crucial for skin wound healing and reducing scars.

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

Thuja orientalis hot water extract may help hair grow by starting the growth phase and improving hair follicle development.

A substance called Vascular Endothelial Growth Factor can protect certain hair follicle stem cells from damage caused by androgens, suggesting a new possible treatment for hair loss.

Experts recommend using evidence-based methods to diagnose and treat hirsutism, focusing on symptoms and underlying causes.

A lotion with natural extracts significantly sped up hair growth in women with hair loss from chemotherapy.

Some vitamins and minerals like vitamin D and iron can help with certain types of hair loss, but more research is needed for others.

Certain skin cells near the base of hair muscles may help renew and stabilize skin, possibly affecting skin disorder understanding.
