Peptide hydrogels heal burn wounds faster and better than standard dressings.

Minoxidil boosts hair growth by increasing cell production and survival.

Alopecia areata is an autoimmune disease causing patchy hair loss, often with other autoimmune disorders, but its exact causes are unknown.

Keratinocytes help heal skin wounds by interacting with immune cells and producing substances that kill pathogens.

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

The niche environment controls stem cell behavior and plasticity, which is important for tissue health and repair.

Stem cell therapy, particularly using certain types of cells, shows promise for treating hair loss by stimulating hair growth and development, but more extensive trials are needed to confirm these findings.

PRP treatment improves hair growth, and the device used can affect results, with some being more effective.
