Activin activation in skin cells speeds up wound healing without affecting scar quality.

Lack or blocking of SRD5a, a key component in hormone creation, can lead to conditions like pseudohermaphrodism and affect hair growth, bone mass, muscle strength, and reproductive health. More research is needed on its regulation from fertilization to adulthood.

Finasteride causes lasting fertility decrease in rats.

The enzymes 5α-reductase and 3α/β-hydroxysteroid oxidoreductase help create brain-active substances from progesterone and testosterone, which could be used for treatment, but more research is needed to ensure their safety and effectiveness.

DA-9401 helps protect rat testis from finasteride damage.

Increased HSD11B1 enzyme expression is linked to higher body fat and insulin resistance.

The osteopontin gene is active in a specific part of rat hair follicles during a certain hair growth phase and might affect hair cycle and diseases.

CBD can either reduce inflammation and not affect hair growth at low levels or inhibit hair growth at high levels.

The X5 Hairlaser might help treat male hair loss, but more research is needed.

Hair density and thickness decrease in all scalp areas for East Asians with AGA.

New treatments for skin diseases are more effective and patient-friendly, but many still lack a cure.

The skin has a complex immune system that is essential for protection and healing, requiring more research for better wound treatment.

Insulin resistance is a key factor in polycystic ovary syndrome, but genetics may also contribute.

PCOS is caused by both genetics and environmental factors like diet and obesity.

Melatonin may help with sleep issues, depression, and cancer, but more research is needed.

Stem cell niches are crucial for regulating stem cell renewal and differentiation, and understanding them can help in developing regenerative therapies.

Platelet-rich plasma with a new carrier significantly increases hair thickness without serious side effects.

Fat-derived stem cells show promise for skin repair and reducing aging signs but need more research for consistent results.

TGF-β signaling is crucial for stem cell maintenance, differentiation, and has implications for cancer treatment.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

Improving skin barrier and using antifungal treatments can help manage dandruff.

Drosha and Dicer are essential for hair follicle health and preventing DNA damage in skin cells.

Air pollution (PM10) increases skin inflammation and aging by reducing collagen and may trigger a repair response in skin cells.

Inactive hair follicle stem cells help prevent skin cancer.

SHBG may be a useful early indicator and treatment target for PCOS.

Brg1 is crucial for hair growth and skin repair by maintaining stem cells and promoting regeneration.

Maintaining the right amount of retinoic acid is crucial for healthy hair and skin.

Hair growth is influenced by various body and external factors, and neighboring hairs communicate to synchronize regeneration.

Effervescent formulations may improve minoxidil delivery, increasing effectiveness and reducing applications needed.

Systemic Lupus Erythematosus has varied symptoms and is hard to diagnose, affecting many body parts and requiring careful clinical judgment.
