Researchers created human hair follicles using a new method that could help treat hair loss.

Platelet-rich plasma with a new carrier significantly increases hair thickness without serious side effects.

Androgens can cause hair growth in some areas and hair loss on the scalp.

The Sonic hedgehog pathway is crucial for new hair growth during mouse skin healing.

Estrogen loss during menopause worsens skin health, but hormone replacement therapy may improve it, though more research is needed.

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.

Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.

Different types of stem cells and their environments are key to skin repair and maintenance.

Oxidative stress contributes to hair graying and loss as we age.

PDGFA/AKT signaling is important for the growth and maintenance of certain skin fat cells.

The document concludes that assessing hair follicle damage due to cyclophosphamide in mice involves analyzing structural changes and suggests a scoring system for standardized evaluation.

Male hormones and their receptors play a key role in hair loss and skin health, with potential new treatments being explored.

Androgens can both stimulate and cause hair loss, and understanding their effects is key to treating hair disorders.

Notch/CSL signaling controls hair follicle differentiation through Wnt5a and FoxN1.
