Hair follicle dermal stem cells are key for regenerating parts of the hair follicle and determining hair type.

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

New hair follicles could be created to treat hair loss.

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

Follicular Cell Implantation might become a new treatment for hair loss and could lead to advances in organ regeneration.

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

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

Different hair growth phases affect how follicles respond to X-rays, and hormones like testosterone and dihydrotestosterone play a key role in baldness; transplanted hair can grow on bald scalp areas.

Minoxidil boosts growth factor in hair cells, potentially promoting hair growth.

Scientists created early-stage hairs from mouse cells that grew into normal, pigmented hair when implanted into other mice.

Different hair growth problems are caused by genetic issues or changes in hair growth cycles, and new treatments are being developed.

Nd:YAG laser can reduce hair with multiple treatments, but permanent removal isn't guaranteed.

The long-pulsed alexandrite laser is effective for hair reduction, particularly for light-skinned individuals with dark hair, but caution is needed for darker skin.

Permanent hair removal is hard, but using longer laser pulses at lower power might improve results.

Dermal papilla cells are key for hair growth and could help us understand and treat hair loss.

Androgens can both increase body hair and cause scalp hair loss.

Sheep hair follicle cells can grow a lot but need the dermal papilla to do so.

VEGF helps hair grow and determines follicle size by increasing blood vessel growth.

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

Scientists found a way to grow human hair cells in a lab that can create new hair when transplanted.

Hair growth is influenced by interactions between skin layers, growth factors, and hormones, but the exact mechanisms are not fully understood.

Improving the environment and cell interactions is key for creating human hair in the lab.

Using a gene therapy with the Sonic Hedgehog gene helps mice regrow hair faster after losing it from chemotherapy.

Using a special stem cell formula on the scalp once a month for six months helped people with hair loss grow more hair.

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

Using microscopes in hair transplants reduces follicle damage.

New treatments for diabetes, central nervous system repair, and cartilage injury were found, and a way to create functional hair follicles from stem cells was developed.

The document concludes that hair biology is complex and there are still unanswered questions about hair loss and follicle changes.

Hair follicle stem cells could be used to treat the skin condition vitiligo.
