The new "whisker follicle microinjection assay" can test how different biomolecules affect hair growth and color.

Advancements in tissue engineering show promise for hair follicle regeneration to treat hair loss.

Mesenchymal stem cells may help treat hair loss by improving hair cell growth and reducing inflammation.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

Minoxidil boosts hair growth by increasing cell production and survival.

Minoxidil affects cell growth in two ways: low doses increase growth, while high doses slow it down and can be toxic.

Minoxidil effectively treats hair loss, with better results in women.

KF19418 promotes hair growth similarly to minoxidil but is not better in live mice.

Researchers created a lab model to study human hair growth, showing it can grow and self-regulate outside the body.

Transplanted baby mouse skin cells grew normal hair using a new, efficient method.

Norgalanthamine helps hair cells grow by activating certain pathways related to hair growth.

Human hair cells can be used to grow new hair on rat ears, suggesting a possible treatment for hair loss.

Blue light helps hair growth by affecting specific proteins in hair follicle cells.

Hibiscus rosa-sinensis leaf extract helps hair grow longer and faster.

Melatonin helps regulate hair growth and protects the hair follicle from stress.

Nerves and chemicals in the body can affect hair growth and loss.

Topical drugs and near-infrared light therapy show potential for treating alopecia.

The document concludes that for hair and feather growth, it's better to target the environment around stem cells than the cells themselves.

Minoxidil speeds up hair growth in rats without prolonging growth phase.

Disrupting Acvr1b in mice causes severe hair loss and thicker skin.

Hair loss treatments include medications and new methods like low-level light therapy, which may work by boosting cell activity and blood flow.

Apigenin may help promote hair growth and could treat hair loss.

Scientists identified three genes important for processing certain brain chemicals, thyroid hormones, and medications.

DHT stops hair regrowth in mice, similar to human hair loss.

Understanding hair follicle biology and stem cell control could lead to new hair loss treatments.

The silk fibroin hydrogel with FGF-2-liposome can potentially treat hair loss in mice.

DA-5512 effectively improves hair growth and health, performing better than minoxidil.

The study created a new model to better understand human hair growth and health.

Mesotherapy is more effective than topical spray for female hair loss treatment.

A specific DNA sequence caused hair loss in male mice by activating immune cells and increasing a certain immune signal.
