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

Minoxidil and finasteride are the main FDA-approved treatments for hair loss, with other methods showing promise but lacking strong evidence.

New app improves storm surge predictions; advances in baldness treatment show potential but require time.

Bioengineering can potentially treat hair loss by regenerating hair follicles and cloning hair, but the process is complex and needs more research.

Safflower (Carthamus tinctorius) extract helps hair grow and could be used in hair products.

FUE hair transplant is a promising method with benefits like less scarring, but requires a skilled surgeon and can damage hair follicles.

Cutting hair follicles into pieces for transplantation results in poor growth and thinner hair, and the technique is more invasive than previously thought.

Transplanted transected hair follicles can survive but grow at unsatisfactory rates and are thinner, suggesting limited potential for unlimited donor hair supply.

Possible new treatments for common hair loss include drugs, stem cells, and improved transplants.

Chemicals from the plant Dicerocaryum senecioides were found to safely speed up and increase hair growth in mice.

Skin needs dermal β-catenin activity for hair growth and skin cell multiplication.

Estrogen affects hair growth and skin cell multiplication.

Bone marrow and umbilical cord stem cells can help grow new hair.

Partial hair follicle extraction can effectively double the number of hair follicles for transplants, with most surviving and growing normally after a year.

Stem cell therapy, particularly using certain types of cells, shows promise for treating hair loss by stimulating hair growth and development, but more extensive trials are needed to confirm these findings.

Stem cell therapy is a promising approach for hair regrowth despite potential side effects.

Basonuclin 2 is vital for the development of facial bones, hair follicles, and male germ cells in adult mice, and its absence can lead to dwarfism and abnormal follicles.

New treatments for hair loss could involve using stem cells and a process called the Wnt/beta-catenin pathway to stimulate hair growth.

Thymosin β4 promotes hair growth by activating stem cells in hair follicles.

Hair follicle regeneration needs special conditions and young cells.

Hedgehog signaling helps keep hair follicle stem cells the same in both young and old human skin.

The study showed that hair follicle stem cells can maintain and organize themselves in a lab setting, keeping their ability to renew and form hair and skin.

Human hair follicle stem cells show signs of low oxygen levels, which may be important for hair growth and preventing baldness.

Gata6 is important for protecting hair growth cells from DNA damage and keeping normal hair growth.

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

Early-stage skin cells help regenerate hair follicles, with proteins SDF1, MMP3, biglycan, and LTBP1 playing key roles.

Inflammation plays a key role in activating skin stem cells for hair growth and wound healing, but more research is needed to understand how it directs cell behavior.

Overexpressing Tβ4 in goats' hair follicles increases cashmere production and hair follicle growth.

Scientists have made progress in understanding hair follicle stem cells, identifying specific genes and markers, and suggesting their use in treating hair and skin conditions.

The document concludes that while "hair follicle cloning" shows promise for unlimited donor hair, it faces challenges with consistency and safety in humans.
