Muscles and nerves that cause goosebumps also help control hair growth.

Environmental factors, hormones, nutrition, and stress all significantly affect skin health and aging.

SHISA6 helps maintain certain stem cells in mouse testes by blocking signals that would otherwise cause them to differentiate.

Researchers created a fully functional, bioengineered skin system with hair from stem cells that successfully integrated when transplanted into mice.

Fat cells are important for healthy skin, hair growth, and healing, and changes in these cells can affect skin conditions and aging.

Birds can regenerate inner ear cells using specific gene pathways, unlike mammals.

The three estrogen receptor genes are highly expressed in zebrafish neuromasts during development.

Blocking the virus's entry into cells by targeting certain pathways could lead to early COVID-19 treatments.

Chitosan nanoparticles improve minoxidil delivery to hair follicles for better alopecia treatment.

Menopause reduces skin collagen and elasticity, and while estrogen therapy can help, its risks require careful consideration.

New treatments for male hypogonadism are effective and should be personalized.

Aromatase gene variation may increase female hair loss risk.

Toxic Shock Syndrome progresses quickly, often involves multiple organs, and is linked to Staphylococcus aureus toxins, with treatment options available but diagnostic challenges remaining.

Mesenchymal stem cells show potential for skin healing and anti-aging, but more research is needed for safe use, especially regarding stem cells from induced pluripotent sources.

Targeting the skin's endocannabinoid system could help treat skin disorders.

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

Aging mice have slower hair regeneration due to changes in signal balance, but the environment, not stem cell loss, controls this, suggesting treatments could focus on environmental factors.

Hair grays due to oxidative stress and fewer functioning melanocytes.

Triparanol therapy can cause hair loss and skin dryness without inflammation or damage to hair follicles or skin structures.

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