Fat tissue under the skin affects hair growth and aging; reducing its inflammation may help treat hair loss.

The skin systems of jawed vertebrates evolved diverse appendages like hair and scales from a common structure over 420 million years ago.

Aging causes hair loss and graying due to stem cell decline and changes in cell behavior and communication.

Stress can cause hair loss by affecting nerve-related hair growth, and noradrenaline might help prevent this.

The nervous system helps control stem cell behavior and immune responses, affecting tissue repair and maintenance.

Skin fat has important roles in hair growth, skin repair, immune defense, and aging, and could be targeted for skin and hair treatments.

Modified stem cells that overexpress a specific protein can improve hair growth and reduce hair abnormalities in mice.

The environment around melanocyte stem cells is key for hair regeneration and color, with certain injuries affecting hair color and potential treatments for pigmentation disorders.

Hair color production in mice is closely linked to the hair growth phase and may also influence hair growth itself.

The skin's internal clock affects healing, cancer risk, aging, immunity, and hair growth, and disruptions can harm skin health.

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

Hair grows faster in the morning and is more vulnerable to damage from radiation due to the internal clock in hair follicle cells.

Hair color production is closely linked to the active growth phase of hair in mice and may also influence hair growth itself.

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

Products should be called 'sperm-safe' only after thorough, well-designed tests.

Adult mice can grow new hair from skin wounds.

Mice can grow new hair follicles after skin wounds through a process not involving existing hair stem cells, but requiring more research to understand fully.

Heparan sulfate is important for hair growth, preventing new hair formation in mature skin, and controlling oil gland development.

Blocking a specific protein signal can make hair grow on mouse nipples.

pH, calcium, and reactive oxygen species regulate plant cell growth, with key roles for NADPH oxidases and plasma membrane H+-ATPases.

Future research on ectodysplasin should explore its role in diseases, stem cells, and evolution, and continue developing treatments for genetic disorders like hypohidrotic ectodermal dysplasia.

Scalp hair grows at 0.37 mm/day, forearm hair at 0.18 mm/day, and thigh hair at 0.30 mm/day, with no significant differences found in people with certain hair conditions.

The document concludes that regenerating functional ectodermal organs like teeth and hair is promising for future therapies.

Mouse touch-sensitive nerve cells adjust their connections based on competition with other similar cells.

Scientists developed tools to observe hair regeneration in real time and assess skin health, using glowing mice and light-controlled genes.

Hair growth is cyclic and influenced mainly by local factors.

The research found that different types of fibroblasts are involved in wound healing and that some blood cells can turn into fat cells during this process.

Hair growth and pigmentation in mice involve specific stages crucial for research.

New single-cell analysis techniques are improving our understanding of stem cells and could help in treating diseases.

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