Trichoscopy helps diagnose and monitor alopecia areata by looking at a combination of specific hair and scalp features.

Alopecia areata is likely caused by a combination of genetic factors and immune system dysfunction, and may represent different diseases with various causes.

Conditioned media from mesenchymal stem cell cultures could be a more effective alternative for regenerative therapies, but more research is needed.

Mice studies show that Protein Phosphatase 2A is crucial for cell growth, development, and disease prevention.

To diagnose hair loss, use a systematic approach including history, exams, and tests.

Trichoscopy is a useful non-invasive method for diagnosing different hair loss conditions.

The article concludes that better understanding gene regulation related to seasonal changes can offer insights into the mechanisms of seasonal timing in mammals.

Mammals might fail to regenerate not because they lack the right cells, but because of how cells respond to their surroundings, and changing this environment could enhance regeneration.

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

The TGF-β family helps control how cells change and move, affecting skin, hair, and organ development.

The conclusion is that tissue structure is key for stem cell communication and maintaining healthy tissues.

Certain genes control the color of human hair by affecting pigment production.

Inherited ichthyoses cause widespread skin scaling and thickening due to gene mutations.

Hair shedding is an active process that could be targeted to treat hair loss.

Etoposide is effective in treating several cancers, especially small cell lung cancer, with acceptable side effects.

Researchers developed a quick and easy way to get and grow cells from the base of human hair follicles.

Stress hormone corticosterone blocks a growth factor to slow down hair stem cell activity and hair growth.

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

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

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

TPA is about 50 times more effective at promoting tumors than MZ.

Dermal Papilla cells are a promising tool for evaluating hair growth treatments.

The document concludes that proper diagnosis and FDA-approved treatments for different types of hair loss exist, but treatments for severe cases often fail and future improvements may focus on hair follicle stem cells.

Hormones, especially androgens, play a key role in acne, which can be a symptom of systemic diseases like PCOS and may require targeted treatment.

Costunolide may have multiple health benefits, including promoting hair growth and protecting against cancer and diabetes, but more research is needed.

The circadian clock influences the behavior and regeneration of stem cells in the body.

Zinc deficiency in children can cause skin issues and can be serious if not diagnosed and treated properly.

Mice lacking a key DNA methylation enzyme in skin cells have a lower chance of activating stem cells necessary for hair growth, leading to progressive hair loss.

S100A4 and S100A6 proteins may activate stem cells for hair follicle regeneration and could be potential targets for hair loss treatments.

HFMs can help study hair growth and test potential hair growth drugs.
