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.

Human skin can make serotonin and melatonin, which help protect and maintain it.

Spironolactone harms fish reproduction and is more potent in fish than invertebrates, needing environmental monitoring.

Annurca apple extract promotes hair growth by changing hair follicle metabolism to boost keratin production.

A young woman had a rare, aggressive ovarian tumor that was hard to diagnose and treat, leading to disease progression despite treatment.

Women with PCOS have higher 5alpha-reductase activity, affecting steroid levels.

Retinoids increase steroid sulfatase activity in leukemia cells through RARα/RXR and involves certain pathways like phosphoinositide 3-kinase and ERK-MAP kinase.

Minoxidil can cause severe body swelling and fluid buildup, which improves after stopping the drug and using diuretics.

The proteins transthyretin and megalin are more present in the growth phase of hair, suggesting they might affect hair health and growth.

Androgens can both promote and prevent hair growth due to differences in gene expression in hair follicles.

Fasting may reduce chemotherapy side effects.

Proteins like aPKC and PDGF-AA, substances like adenosine and ATP, and adipose-derived stem cells all play important roles in hair growth and health, and could potentially be used to treat hair loss and skin conditions.

Changes in gut bacteria can contribute to the development of Polycystic Ovary Syndrome (PCOS), affecting metabolism, immunity, and causing inflammation. Treatments may involve adjusting these factors.

Different types of skin on mice have unique chemical profiles related to how they grow and react to stress.

We need to learn more about 5α-reductases and neuroactive steroids to safely make drugs targeting these enzymes.
