Damaging mitochondrial DNA in mice speeds up aging due to increased reactive oxygen species, not through the p53/p21 pathway.

Wnt proteins from certain skin cells are crucial for normal hair growth and renewal.

Scalp cooling to prevent hair loss from chemotherapy works for some but not all, and studying hair damage markers could improve prevention and treatment.

Keratinocytes control how melanocytes work.

Understanding skin structure and development helps diagnose and treat skin disorders.

The WNT signaling pathway is important in many diseases and targeting it could offer new treatments.

Hair gets thinner, grayer, and changes texture with age due to genetics, environment, and cellular changes, affecting the growth cycle.

Annurca apple extract may protect mouse hair from damage by chemotherapy and could help treat hair loss without promoting cancer growth.

PDGF-BB helps young melanocytes grow but stops mature ones from growing, and it makes melanocytes more specialized.

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

Human hair follicle organ culture is a useful model for hair research with potential for studying hair biology and testing treatments.

Caffeine applied to the scalp can protect hair follicles from UV damage.

Escin may help treat hair loss by boosting a specific cell growth pathway.

Notch signalling helps skin cells differentiate and prevents tumors.

Circadian clock genes are important for hair growth and may affect aging-related hair loss and graying.

Hair growth and health are influenced by factors like age, environment, and nutrition, and are controlled by various molecular pathways. Red light can promote hair growth, and understanding these processes can help treat hair-related diseases.

UV exposure causes hair thinning, graying, and changes in hair growth cycles in mice.

Radiation therapy damages skin structure and immune function, causing inflammation and potential hair loss.

Zebrafish are useful for studying and developing treatments for human skin diseases.

Regenerative medicine shows promise for improving hair and skin but needs more research for standard use.

The conclusion suggests that focusing on certain cellular pathways may improve the prevention and repair of hair loss caused by radiotherapy.

Prdm1 is necessary for early whisker development in mice but not for other hair, and its absence changes nerve and brain patterns related to whiskers.

Stress may trigger hair loss by affecting immune protection in hair follicles.

New research shows that skin diversity is influenced by different types of dermal fibroblasts and their development, especially involving the Wnt/β-catenin pathway.

Eating fewer calories may slow skin aging and improve skin health through various biological changes.

Hair follicle cells age faster and lose pigment due to less catalase, causing hair to turn gray.

Certain genes are more active in baby scalp cells and can help grow hair when added to adult mouse skin cells.

P-cadherin is important for hair growth and health, and its problems can cause hair and skin disorders.

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

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