Skin and hair can regenerate after injury due to changes in gene activity, with potential links to how cancer spreads. Future research should focus on how new hair follicles form and the processes that trigger their creation.

Nerve signals are crucial for hair follicle stem cells to become skin stem cells and help in wound healing.

Follistatin helps hair growth and cycling, while activin prevents it.

Certain drugs can cause early hair growth in mice by affecting the nerves.

CTE and FPHL are different hair loss types with unique causes.

Nanoparticles can be used to deliver drugs to hair follicles, potentially improving treatments for conditions like acne and alopecia, and could also be used for vaccine delivery and gene therapy.

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

Aging causes hair to gray and thin, with the timing of graying varying by race, and factors like oxidative stress and genetics can lead to hair loss.

Applying a special compound can promote hair growth without harmful side effects.

Glutamine metabolism affects hair stem cell maintenance and their ability to change back to stem cells.

Chemokine signaling is important for hair development.

α3β1-integrin is crucial for maintaining normal hair follicle shape and function but not needed for the development of the surrounding skin.

New cells are added to the hair's dermal papilla during the active growth phase.

White wax and policosanol from white wax effectively reduced hair loss and promoted hair growth in mice better than a known hair growth drug.

Men with hair loss have more DNA changes in back-of-head hair follicles, possibly protecting them from thinning.

A mix of 5-aminolevulinic acid and iron ion can speed up hair growth.

No link found between specific genes and female pattern hair loss.

Scientists created keratinocyte cell lines from human hair that can differentiate similarly to normal skin cells, offering a new way to study skin biology and diseases.

The conclusion is that teeth, hair, and claws have similar stem cell niches, which are important for growth and repair, and more research is needed on their regulation and potential markers.

Scaffold improves hair growth potential.

The document concludes that hair analysis is not good for assessing nutrition but can detect long-term heavy metal exposure.

Extracts from three Polynesian plants were found to promote hair growth by affecting cell growth and gene expression related to hair.

Eplerenone, a mineralocorticoid receptor antagonist, was found to promote hair growth in human hair follicles.

Hair loss in a drug reaction case involved both a common shedding phase and an immune attack on hair follicle stem cells.

Forensic hair analysis for drugs is now more reliable and accurate.

Hair health is influenced by genetics, aging, and environmental factors, with proper care needed to maintain it.

Proteins like aPKC and PDGF-AA, substances like adenosine and ATP, and adipose-derived stem cells all play important roles in hair growth and health, and could potentially be used to treat hair loss and skin conditions.

Understanding gene expression in hair follicles can reveal insights into hair growth and disorders.

β-catenin in the dermal papilla is crucial for normal hair growth and repair.
