Dihydrotestosterone (DHT) mainly affects nearby cells, doesn't significantly change prostate hormonal environment or cancer risk, and doesn't play a main role in causing hair loss or acne. More research is needed on its effects on heart health, sexual function, and bone health.

Finasteride for hair loss may cause long-lasting side effects like impotence and low libido, but trials lack proper safety reporting.

The 3D skin model is better for hair growth research and testing treatments.

Scientists developed a method to grow human fetal skin and digits in a lab for 3-4 weeks, which could help study skin features and understand genetic interactions in tissue formation.

The article concludes that developing in vitro models for human hair structures is important for research and reducing animal testing, but there are challenges like obtaining suitable samples and the models' limitations.

The conclusion is that we need more effective hair loss treatments than the current ones, and these could include new drugs, gene and stem cell therapy, hormones, and scalp cooling, but they all need thorough safety testing.

A girl with hereditary chorea, likely Huntington's disease, had her condition worsened by lupus.

The project created a standardized system for classifying skin lesions in lab rats and mice.

A kimchi-derived bacterium could help whiten teeth and prevent bad breath.

A 66-year-old woman with skin lesions and other symptoms improved after treatment for porphyria cutanea tarda.

Bioprinting could greatly improve health outcomes but faces challenges like material choice and ensuring long-term survival of printed tissues.

Targeting colon cancer stem cells might lead to better treatment results.

The document concludes that using LC-MS/MS for measuring androgens is more accurate than older methods, but it needs careful validation and standardized references to be most effective.

Stress stops hair growth in mice by causing early hair growth phase end and harmful inflammation through a specific nerve-related pathway.

Different scaffold patterns improve wound healing and immune response in mouse skin, with aligned patterns being particularly effective.

Human hair protein modifications could potentially indicate heart disease risk.

Hutchinson-Gilford Progeria Syndrome is a rare genetic disorder caused by a specific gene mutation, characterized by aging symptoms and managed by monitoring heart health and using low-dose aspirin.

Polycystic ovary syndrome costs the U.S. over $4 billion a year, mainly from treating related health issues.

Niacinamide improves aging skin and is safe for use in cosmetics.

The conclusion is that early diagnosis and a multi-system treatment approach are crucial for managing PCOS and its associated health risks.

People with diabetes or obesity should manage their conditions carefully as they have a higher risk of severe COVID-19.

Different treatments for alopecia areata have varying success rates and side effects; intralesional steroids are most effective.

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

Fibromodulin treatment helps reduce scarring and improves wound healing by making it more like fetal healing.

Dutasteride makes alcohol less sedating and may lead to less drinking in men.

APS-1 in Italy shows diverse AIRE mutations and various autoimmune issues.

The research concluded that selection significantly shaped the genetic variation of the X chromosome, with certain regions affected by past selective events.

CIP/KIP proteins help stop cell division and support hair growth.

Most hair loss in captive rhesus macaques is likely due to environmental and behavioral factors.

Animal models are crucial for learning about hair loss and finding treatments.
