Male hormones, particularly DHT, are linked to male pattern hair loss, and treatments like finasteride can help, but they don't work for postmenopausal women's hair loss, which may have different causes.

Estrogens significantly influence hair growth by interacting with receptors in hair follicles and may help regulate the hair growth cycle.

Early diagnosis and individualized treatment improve outcomes for Congenital Adrenal Hyperplasia.

Hair loss increases with age; alcohol raises risk, more female partners lowers it.

Minoxidil treats hair loss, promotes growth, has side effects, and has recent patents.

About 2.2% of women with symptoms of high male hormones have a mild form of congenital adrenal hyperplasia, and measuring a specific hormone level can accurately diagnose it.

Skin aging is due to impaired stem cell mobilization or fewer responsive stem cells.

Too much androgen can cause hair loss; finasteride may help.

Eating less sugar, milk, and saturated fats and more vegetables and fish may help treat and prevent acne.

Finasteride treats enlarged prostate and hair loss, but may cause side effects in some patients.

Stem cell therapy, particularly using certain types of cells, shows promise for treating hair loss by stimulating hair growth and development, but more extensive trials are needed to confirm these findings.

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

The conclusion is that PCOS is caused by ovarian sensitivity to hormones and disrupted hormone control, possibly due to ovarian factors, and more research is needed.

Allergic reactions to blood thinners are rare but can be serious, requiring careful testing and alternative treatments.

Estrogen Receptor ß (ERß) is the main hormone controller in human skin and hair follicles, not Estrogen Receptor α (ERα) or the Androgen Receptor (AR).

Mouse hair follicle cells briefly grow during the early hair growth phase, showing that these cells are important for starting the hair cycle.

"Male-pattern" hair loss is common in women, especially after menopause, and doesn't always mean there's a problem with hormone balance.

Obesity worsens PCOS symptoms, and PCOS may lead to more weight gain; managing both requires a holistic approach that includes mental health.

Prolactin contributes to hair loss by promoting hair follicle shrinkage and cell death.

Mice hair growth patterns get more complex with age and can change with events like pregnancy or injury.

Men generally have more severe COVID-19 cases and higher death rates than women due to biological differences.

Stress can cause hair loss by negatively affecting hair follicles and this effect might be reversed with specific treatments.

Targeting androgen receptors could be a promising way to treat skin disorders with fewer side effects.

Polycystic Ovary Syndrome likely starts in childhood and may be genetic and influenced by early hormone exposure.

New targets for making and using brain-synthesized steroids could lead to better treatments for brain disorders and alcoholism.

The telogen phase of hair growth is active and important for preparing hair follicles for regeneration, not just a resting stage.

Vitamin D has potential benefits for cancer prevention, heart health, diabetes, obesity, muscle function, skin health, and immune function, but clinical results are mixed and more research is needed.

Fibroblast growth factor receptor signaling controls cell development and repair, and its malfunction can cause disorders and cancer, but it also offers potential for targeted therapies.

The document concludes that while significant progress has been made in understanding skin biology and stem cells, more research is needed to fully understand their interactions with their environment.

Most women with PCOS have high levels of male hormones, and free testosterone is the best marker for this.
