Spiny mice are better at regenerating hair after injury than laboratory mice and could help us understand how to improve human skin repair.

The "Punch Assay" can regenerate hair follicles efficiently in mice and has potential for human hair regeneration.

The shampoo with grapefruit peel and Gleditsia sinensis helps mice grow hair faster, more, and longer.

The technique can potentially treat hair loss by using a matrix to grow new hair from cells.

Mice are useful for researching human hair loss and testing treatments, despite some differences between species.

Progranulin overexpression leads to shorter, thinner hair and increased cell death in mouse hair follicles.

Mouse models help understand alopecia areata and find treatments.

Researchers created a mouse with the same mutation as humans with trichothiodystrophy, showing similar symptoms and confirming the condition is due to defects in DNA repair and gene activity.

A new painless method to collect hair follicles helps study DNA damage and aging.

Ionizing radiation causes irreversible skin damage, with single doses leading to acute injury and hair graying, and fractional doses causing more severe long-term tissue damage.

Wnt signaling is crucial for skin and hair development and its disruption can cause skin tumors.

Researchers found a new way to create hair-growing structures in the lab that can grow hair when put into mice.

The study found new details about human hair growth and suggests that preventing a specific biological pathway could potentially treat hair graying.

Aging mice have slower hair regeneration due to changes in signal balance, but the environment, not stem cell loss, controls this, suggesting treatments could focus on environmental factors.

The engineered skin substitute helped grow skin with hair on mice.

KAP-depleted hair causes less immune response and is more biocompatible for implants.

Removing Dicer from pigment cells in newborn mice causes early hair graying and changes in cell migration molecules.

AP collagen peptides help hair grow and improve hair health.

Wnt1a-conditioned medium from stem cells helps activate cells important for hair growth and can promote hair regrowth.

Organotypic culture systems can grow skin tissues that mimic real skin functions and are useful for skin disease and hair growth research, but they don't fully replicate skin complexity.

Hair growth is influenced by factors like genetics and nutrition, and more research is needed to understand hair loss and growth mechanisms.

Old people have less hair because their hair follicles don't regenerate as well, not because of fewer stem cells, and a protein called follistatin might help reactivate hair growth.

Immune cells are crucial for hair growth and preventing hair loss.

Future hair loss treatments should aim to extend hair growth, reactivate resting follicles, reverse shrinkage, and possibly create new follicles, with gene therapy showing promise.

CARI ONE helps start hair growth and makes hair follicles bigger and more numerous.

SKPs are similar to adult skin stem cells and could help in skin repair and hair growth.

Human beard hair medulla contains a unique and complex mix of keratins not found in other human tissues.

Mice lacking a key DNA methylation enzyme in skin cells have a lower chance of activating stem cells necessary for hair growth, leading to progressive hair loss.

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

Some medications might reverse gray hair, especially those that reduce inflammation or stimulate pigment production, and vitamin B might help.
