Thai people's hair density decreases with age and varies by scalp area, but hair thickness stays the same regardless of age or scalp area.

Epidermal stem cells have various roles in skin beyond just maintenance, including forming specialized structures and aiding in skin repair and regeneration.

Adipose-derived stem cells show potential for skin rejuvenation and wound healing but require more research to overcome challenges and ensure safety.

Exosomes from umbilical cord cells fix hearing loss and damaged ear hair cells in mice.

A specific group of slow-growing stem cells marked by Thy1 is crucial for skin maintenance and healing in mice.

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

PNKP is essential for keeping adult mouse progenitor cells healthy and growing normally.

Androgens play a key role in hair growth and disorders like baldness and excessive hairiness.

Skin aging reflects overall body aging and can indicate internal health conditions.

New treatments for hair loss show promise, including plasma, stem cells, and hair-stimulating complexes, but more research is needed to fully understand them.

Activating Wnt in skin cells controls the number of hair follicles by directing cell movement and fate.

DNMT3A is crucial for healthy skin and hair growth.

Both Th1 and Th2 immune responses are increased in alopecia areata, with Th2 response more strongly linked to how severe the disease is.

Activating Nrf2 helps wounds heal faster by increasing hair follicle stem cells.

Topical tofacitinib is effective in promoting hair growth for non-scarring alopecia.

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

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

Aging causes sweat glands to shrink, leading to skin issues, and blue light can help hair grow.

Blue light helps hair growth by affecting specific proteins in hair follicle cells.

Arrector pili muscle regulates hair follicle stem cells, DNA methylation needed for hair cycling, and Wnt/B-catenin signaling starts hair growth.

BMPs are crucial for hair growth and their decrease by androgens leads to hair loss.

Skin cells show flexibility in healing wounds and forming tumors, with potential for treating hair disorders and chronic ulcers.

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

Hair follicle stem cells from Arbas Cashmere goats can become fat, nerve, and liver cells.

BMP2 helps hair follicle stem cells become specialized by increasing PTEN, which causes autophagy.

A two-step method was created in 2015 to make more cells that help with hair growth, but they need to be combined with other cells for 4 days to actually form new hair.

Advancements in tissue engineering show promise for hair follicle regeneration to treat hair loss.

PTEN helps control the number and health of skin stem cells by working with the protein BMAL1.

Stem cells and their secretions could potentially treat stress-induced hair loss, but more human trials are needed.

The JAK/STAT pathway is important in cell processes and disease, and JAK inhibitors are promising for treating related conditions.
