Gray hair is caused by reduced melanin production or transfer issues, linked to aging and possibly health conditions, with treatments focusing on color camouflage.

Hair graying is influenced by factors like nerves, fat cells, and immune cells, not just hair follicles.

Melanocytes are important for skin and hair color and protect the skin from UV damage.

The research reveals how early embryonic mouse skin develops from simple to complex structures, identifying various cell types and their roles in this process.

Chemotherapy often causes hair loss, which usually grows back within 3 to 6 months, but there's no effective treatment to prevent it.

The research found ways to activate melanocyte stem cells for potential treatment of skin depigmentation conditions.

Cosmeceuticals may benefit skin health but need more research for efficacy and safety confirmation.
