Epithelial-mesenchymal interactions control hair growth cycles through specific molecular signals.

Melanocyte stem cells in hair follicles are key for hair color and could help treat greying and pigment disorders.

The conclusion is that proper signaling is crucial for hair growth and development, and errors can lead to cancer or hair loss.

The document provides a method to classify human hair growth stages using a model with human scalp on mice, aiming to standardize hair research.

Lactate production is important for activating hair growth stem cells.

Bone Morphogenetic Proteins (BMPs) help control skin health, hair growth, and color, and could potentially be used to treat skin and hair disorders.

Wnt signaling controls whether hair follicle stem cells stay inactive or regenerate hair.

Hair follicle stem cells are key for hair and skin regeneration, can be reprogrammed, and have potential therapeutic uses, but also carry a risk of cancer.

The Sonic hedgehog pathway is crucial for new hair growth during mouse skin healing.

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.

The telogen phase of hair growth is active and important for preparing hair follicles for regeneration, not just a resting stage.

Hair follicles are hormone-sensitive and involved in growth and other functions, with potential for new treatments, but more research is needed.

Activating the Wnt/β-catenin pathway could lead to new hair loss treatments.

Muscles and nerves that cause goosebumps also help control hair growth.

Cells in hair follicles help create fat cells in the skin by releasing a protein called Sonic Hedgehog.

The conclusion is that hair growth can be improved by activating hair cycles, changing the surrounding environment, healing wounds to create new hair follicles, and using stem cell technology.

Exosomes from dermal papilla cells help hair growth by making hair follicle stem cells multiply and change.

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.

Understanding how hair follicle stem cells work can help find new ways to prevent hair loss and promote hair growth.

Environmental factors at different levels control hair stem cell activity, which could lead to new hair growth and alopecia treatments.

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

Two-photon microscopy helps observe hair follicle stem cell behaviors in mice.

Brain hormones significantly affect hair color and could potentially be used to prevent or reverse grey hair.

Wnt10b makes hair follicles bigger, but DKK1 can reverse this effect.

miR-22, a type of microRNA, controls hair growth and its overproduction can cause hair loss, while its absence can speed up hair growth.

Lymphatic vessels are essential for hair follicle growth and skin regeneration.

Hoxc genes control hair growth through Wnt signaling.

Hair follicle regeneration possible, more research needed.

Hormones and neuroendocrine factors control hair growth and color, and more research could lead to new hair treatment options.
