Restoring mitochondrial function in mice reversed their skin wrinkling and hair loss.

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.

Hair greying is linked to reduced ATM protein in hair cells, which protects against stress and damage.

Human skin has less GDNF and its receptor with age.

Eating less can improve stem cell function and increase lifespan.

Progeroid mouse models show signs of early aging similar to humans, helping us understand aging better.

Fluorescence can effectively measure acne treatment progress.

New culture method keeps human skin stem cells more stem-like.

Men's facial rejuvenation involves unique challenges and is increasingly popular, with many opting for nonsurgical treatments.

Cell-based models help test if cosmetic ingredients really work for hair growth and skin health.

Hair restoration surgery redistributes existing hair to achieve a natural look, with visible regrowth in 3-4 months and rare complications, mostly aesthetic.

The document suggests that activating autophagy might help with regeneration by removing old and damaged cells.

Zinc oxide nanoparticles in sunscreen do not penetrate deep into the skin.

Skin problems are very common in people with end-stage kidney disease.

Astaxanthin is a safe antioxidant that may improve heart, skin, eye health, and physical performance, and help manage chronic diseases.

More hair loss leads to higher risk of psychosexual disorders, especially in women.

The document concludes that sex hormones are crucial for mammalian reproduction, health, and behavior, and require more research for therapeutic use.

Human hair shows promise for non-invasive medical testing, but more research is needed to standardize its use.

DHEA improved brain function and behavior in old monkeys and had additional health benefits.

The 2015 Hair Research Congress concluded that stem cells, maraviroc, and simvastatin could potentially treat Alopecia Areata, topical minoxidil, finasteride, and steroids could treat Frontal Fibrosing Alopecia, and PTGDR2 antagonists could also treat alopecia. They also found that low-level light therapy could help with hair loss, a robotic device could assist in hair extraction, and nutrition could aid hair growth. They suggested that Alopecia Areata is an inflammatory disorder, not a single disease, indicating a need for personalized treatments.

Oxidative stress causes hair to gray by damaging and killing pigment cells.

Hair loss might be linked to eye aging due to inflammation markers in blood.

Hair stem cells produce a protein called COL17A1 that plays a key role in their development and is linked to hair thinning and baldness.

The document concludes that adult mammalian skin contains multiple stem cell populations with specific markers, important for understanding skin regeneration and related conditions.

Human foreskin does not show aging or reduced cell growth after radiation, and H2A.J is not a good marker for radiation-induced aging.

Hormones affect prostate health and disease, with certain hormone imbalances linked to prostate cancer and benign prostatic hyperplasia.

EAAT4 decreases with age, harming skin function and calcium balance.

Exosomes from human hair follicle cells can improve aging hair follicle cell function and help regenerate hair follicles.

Aging changes female scalp cells, likely affecting hair health.
