Light can activate hair growth through a pathway from the eyes to hair follicles.

The article concludes that developing in vitro models for human hair structures is important for research and reducing animal testing, but there are challenges like obtaining suitable samples and the models' limitations.

Key genes and RNA networks regulate hair growth and follicle density in Rex rabbits.

Skin health and repair depend on the signals between skin stem cells and their surrounding cells.

Androgens prevent hair growth by changing Wnt signals in cells.

Using a fractional laser can stimulate hair growth, but the intensity and duration of inflammation are crucial. Too much can cause ulcers and scarring. Lower beam energy and fewer treatments are recommended to avoid damage.

The study showed that some hair follicle stem cells wake up to grow hair while others stay asleep, and that the environment around them is important for hair growth.

FA2H is essential for normal fur and sebum production in mice.

Some breast cancer chemotherapy can cause permanent hair loss.

Hair follicle regeneration in skin grafts may be possible using stem cells and tissue engineering.

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

PDGF signaling is crucial for maintaining and renewing hair follicle stem cells, which could help treat hair loss.

Gamma-rays exposure during the resting phase of hair growth can damage hair regeneration and color in mice.

MIM is crucial for hair follicle formation and regeneration by controlling cilia formation and hedgehog signaling through its interaction with Cortactin and Src.

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

AA-PRP injections effectively increase hair count and thickness for male pattern hair loss.

PTEN helps control the number and health of skin stem cells by working with the protein BMAL1.

The OVOL1 gene, controlled by β-catenin, is crucial for creating hair follicles.

The protein EZH2 blocks microRNA-22, increasing STK40 protein, which helps hair follicle stem cells change and grow 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.

Thymic stromal lymphopoietin (TSLP) promotes hair growth, especially after skin injury.

Skin stem cells interacting with their environment is crucial for maintaining and regenerating skin and hair, and understanding this can help develop new treatments for skin and hair disorders.

The conclusion is that understanding how hair follicle stem cells live or die is important for maintaining healthy tissue and repairing injuries, and could help treat hair loss, but there are still challenges to overcome.

Human hair follicle organ culture is a useful model for hair research with potential for studying hair biology and testing treatments.

Chinese herbal medicine can help treat hair loss by promoting hair growth and preventing cell death, maintaining a balance between hair growth and loss.

Wounds can cause new hair growth in adult mice, influenced by Wnt signaling.

Dying cells can help with faster healing and new hair growth by releasing a growth-promoting molecule.

Hes1 protein is important for hair growth and regeneration, and could be a potential treatment for hair loss.

DNA methylation is essential for skin and hair follicle development, and could be a target for treating skin diseases.

sPLA2-IIE is crucial for normal hair follicle structure and skin health.
