Androgens like testosterone affect skin health and can lead to conditions such as acne and hair loss, with various treatments available.

Human scalp hair follicles have PGE2 and its receptors, which might affect hair growth.

Hormones significantly affect skin health, with vitamin D playing a key role.

The document concludes that understanding hair follicle biology can lead to better hair loss treatments.

Epigenetic changes control how adult stem cells work and can lead to diseases like cancer if they go wrong.

High androgen levels in young women with PCOS are linked to higher blood pressure.

Estrogen loss during menopause worsens skin health, but hormone replacement therapy may improve it, though more research is needed.

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

Melanocytes are crucial for skin pigmentation and can affect conditions like melanoma, vitiligo, and albinism, as well as hair color and hearing.

Menopause reduces skin collagen and elasticity, and while estrogen therapy can help, its risks require careful consideration.

RANK-RANKL signaling is essential for hair growth and skin health.

Adrenal disorders can cause lasting brain and behavior issues in children.

Measuring reproductive hormones in brown bear hair could help identify their sex and reproductive state, but better collection methods or lab techniques are needed.

The conclusion is that future hair loss treatments should target the root causes of hair thinning, not just promote hair growth.

Betacoronaviruses, like COVID-19, may cause hormone system dysfunction and affect disease susceptibility and severity.

Understanding how epigenetic regulation affects stem cells is key to cancer insights and new treatments.

Male hormones cause different growth in identical human hair follicles due to their unique epigenetic characteristics.

AKR1D1 controls glucocorticoid levels and receptor activity in liver cells.

COVID-19 and hypopituitarism (reduced pituitary gland function) are linked, with the latter's related health issues potentially worsening COVID-19 outcomes, and COVID-19 possibly increasing risk for pituitary complications.

Using PGPR as biofertilizers can improve soil health and plant growth while reducing reliance on synthetic fertilizers.

Some hair loss and prostate drugs might increase the risk of diabetes and heart disease.

Finasteride doesn't affect erections much, but may decrease libido in men.

SARS-CoV-2, the virus causing COVID-19, can affect all endocrine organs and systems, altering their function and potentially leading to disorders. Factors like diabetes and obesity increase infection risk and severity. Understanding these effects is key for effective treatment.

c-kit affects hair growth and color in alopecia areata and androgenetic alopecia.

Targeting the protein Caveolin-1 might help treat a type of scarring hair loss called Frontal Fibrosing Alopecia.

Researchers identified genes in scalp hair follicles that may affect hair traits and hair loss.

The document explains the difficulty in diagnosing and treating brain diseases caused by the immune system and stresses the need for quick and accurate tests.

Most adrenal cortex tumors are benign and non-secreting, but proper diagnosis and treatment are important due to the rare possibility of cancer.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

Understanding skin structure and development helps diagnose and treat skin disorders.
