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

Ruby laser pulses best destroy hair follicles during the growth phase and effectiveness varies with laser intensity; melanin is key for targeting, and timing treatments can improve results.

Hedgehog signaling helps keep hair follicle stem cells the same in both young and old human skin.

Hair can regrow after certain stem cells are lost because other stem cells can take over their role.

Research on epidermal stem cells has advanced significantly, showing promise for improved clinical therapies.

The article concludes that hair loss is a common side effect of drugs treating skin cancer by blocking the hedgehog pathway, but treatment should continue, and more selective drugs might prevent this side effect.

Skin cell-derived vesicles can help heal skin injuries effectively.

Targeting the protein Caveolin-1 might help treat a type of scarring hair loss called Frontal Fibrosing Alopecia.

PRC1 is essential for proper skin development and stem cell formation by controlling gene activity.

Different types of inactive melanocyte stem cells exist with unique characteristics and potential to develop into other cells.

ΔNp63α helps control a protein that stops cancer cells from spreading.

Colchicine can inhibit hair growth by affecting cell activity and protein expression in hair follicles.

Mesenchymal stem cell therapy may help treat alopecia areata by promoting hair growth and reducing inflammation.

Researchers found that the Leptin receptor is a consistent marker for hair follicle dermal cells, which may help future hair research.

Too much β-catenin activity can mess up the development of mammary glands and make them more like hair follicles.

Telogen is an active phase with important biological processes, not a resting phase.

Wnt signaling is crucial for pigmented hair regeneration by controlling stem cell activation and differentiation.

Estrogens significantly influence hair growth by interacting with receptors in hair follicles and may help regulate the hair growth cycle.

Skin aging is due to impaired stem cell mobilization or fewer responsive stem cells.

Exosomes could potentially enhance tissue repair and regeneration with lower rejection risk and easier production than live cell therapies.

The nude gene causes skin cell overgrowth and improper development, leading to hair and urinary issues.

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

Stem cell differentiation is crucial for skin barrier maintenance and its disruption can lead to skin diseases.

Indian Hedgehog helps control skin cell growth and protects against aggressive skin cancer.

Scientists identified a unique type of human skin stem cell that could help with tissue repair.

Low-Level Laser Therapy can stimulate healing and cell function, potentially leading to wider medical use.

Wnt and Notch signaling help wound healing by promoting cell growth and regulating cell differentiation.

Eph/ephrin signaling is important for skin cell behavior and could be targeted to treat skin diseases.

BMP signaling is important for skin color, affecting melanin production, pigment spread, and cell movement.

The research found that a specific skin cell type not only triggers hair growth but also controls hair color, and that aging can lead to hair loss and color changes.
