Different types of stem cells in hair follicles play unique roles in wound healing and hair growth, with some stem cells not originating from existing hair follicles but from non-hair follicle cells. WNT signaling and the Lhx2 factor are key in creating new hair follicles.

The new hydrogel with zinc and polysaccharides improves wound healing and has antibacterial properties.

Glutamine metabolism affects hair stem cell maintenance and their ability to change back to stem cells.

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

Non-coding RNAs are important for hair growth and could lead to new hair loss treatments, but more research is needed.

Foxp3+ Regulatory T Cells are important for immunity and tolerance, affect hair growth and wound healing, and their dysfunction can contribute to obesity-related diseases and other health issues.

Twist1 helps maintain important features of cells crucial for hair growth by working with Tcf4 and β-catenin.

Cholesterol balance is important for hair health, and problems with it can lead to hair loss conditions.

A man's forehead and eyebrow were successfully reconstructed with a skin and hair graft that matched his other eyebrow, without needing frequent trimming.

RAPK is a rare skin disorder with pigmented spots, mainly on hands and feet, starting in youth.

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.
