Aging causes sweat glands to shrink and move upward, leading to less elastic skin and more wrinkles.

People with alopecia areata had lower vitamin D levels, but these levels didn't relate to many aspects of the condition.

New treatments targeting skin stem cells show promise for skin repair, anti-aging, and cancer therapy.

Single Blimp1+ cells can create functional sebaceous gland organoids in the lab.

Blood tests can help understand the genetic differences in people with alopecia areata, including how severe it is and if it's inherited.

Skin aging is caused by stem cell damage and can potentially be delayed with treatments like antioxidants and stem cell therapy.

A mutation in the Adam10 gene causes freckle-like spots on Hairless mice.

Hydroxypinacolone retinoate is a potent anti-aging ingredient for skin that is more effective and less irritating than other forms of retinoids.

Different types of stem cells help maintain and heal skin.

Hataedock treatment improved skin health and reduced atopic dermatitis symptoms by enhancing the skin barrier and reducing inflammation.

Reflectance spectroscopy can noninvasively track hair growth stages by measuring skin reflectance and melanin changes.

Light can turn on hair growth cells through a nerve path starting in the eyes.

A position effect on the TRPS1 gene causes excessive hair growth in humans and mice.

Monkeys with hair loss during pregnancy showed higher stress hormone levels and invested differently in their offspring.

Mice can correct hair follicle orientation without certain genes, but proper overall alignment needs those genes.

Keratin 26 affects cashmere goat hair growth and is influenced by various treatments.

The article concludes that hair loss is a common side effect of drugs treating skin cancer by blocking the hedgehog pathway, but treatment should continue, and more selective drugs might prevent this side effect.

Wnt signaling is important for development and cell regulation but can cause diseases like cancer when not working properly.

Skin patterns are formed by simple reaction-diffusion mechanisms.

Mouse touch-sensitive nerve cells adjust their connections based on competition with other similar cells.

Skin development in mammals is controlled by key proteins and signals from underlying cells, involving stem cells for maintenance and repair.

Smad4 is important for healthy hair follicles because it helps produce a protein needed for hair to stick together and grow.

The document concludes that stem cells and their environments are crucial for skin and hair health and have potential for medical treatments.

PBX1 helps reduce aging and cell death in hair follicle stem cells by decreasing DNA damage, not by improving DNA repair.

The best animal model for studying male-pattern baldness is the stumptailed macaque, not rats or mice.

Hair can regrow in adult mice's skin after injury, and this process can be boosted by increasing Wnt7a, a protein. This could potentially help treat baldness and change our understanding of hair growth.

Mice with too much sPLA₂-IIA have hair loss and poor wound healing due to abnormal hair growth and stem cell depletion.

Gamma rays did not change hair follicle density but increased white and hypopigmented hairs in mice.
