The nucleus is key in controlling skin growth and repair by coordinating signals, gene regulators, and epigenetic changes.

The conclusion is that the nuclear lamina and LINC complex in skin cells respond to mechanical signals, affecting gene expression and cell differentiation, which is important for skin health and can impact skin diseases.

A device was made in 2008 to measure hair loss severity. Other findings include: frizzy mutation in mice isn't related to Fgfr2, C/EBPx marks preadipocytes, Cyclosporin A speeds up hair growth in mice, blocking plasmin and metalloproteinases hinders healing, hyperbaric oxygen helps ischemic wound healing, amniotic membranes heal wounds better than polyurethane foam, rhVEGF165 from a fibrin matrix improves tissue flap viability and induces VEGF-R2 expression, and bFGF enhances wound healing and reduces scarring in rabbits.

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

Hair follicle studies suggest that maintaining telomere length could help treat hair loss and graying, but it's uncertain if mouse results apply to humans.

More high-quality research is needed to recommend flavonoids and saponins for clinical use.

Hair dye ingredient PPD causes cell death and aging in human hair cells by altering microRNA levels.

Vitamin B3 may help prevent hair loss and promote hair growth by protecting scalp cells from stress and reducing hair growth-blocking proteins.

Plant extracts may help prevent or reverse hair graying.

Low oxygen areas help maintain and protect blood stem cells by using a simple sugar breakdown process for energy and managing their activity levels.

Baricitinib reduces inflammation and improves cell health in premature aging cells.

Non-coding RNAs could help detect and treat radiation damage.

SIRT7 protein is crucial for starting hair growth in mice.

Camellia japonica extract may improve scalp health and promote hair growth.

Oxidative stress and immune dysfunction are linked to both Hashimoto's thyroiditis and polycystic ovary syndrome, with diet and specific treatments important for managing these conditions.

Melatonin improves cashmere goat hair quality by increasing follicles and reducing skin aging.

Aging reduces skin stem cell function, leading to changes like hair loss and slower wound healing.
