Minoxidil and finasteride can slow hair loss and stimulate regrowth, but won't restore all lost hair or reverse complete baldness.

Dutasteride protects dopamine neurons in Parkinson's mice, but Finasteride doesn't.

Melatonin implants can change the seasonal prolactin levels and hair growth in adult cashmere goats but not in juveniles, and don't delay spring moult for better fiber harvesting.

Men, particularly those with hair loss, are more likely to get the virus, and those with prostate cancer may have milder symptoms. Testosterone's role in the disease is unclear, and the virus doesn't seem to harm male fertility. Women with PCOS might be at higher risk. More research is needed.

Smoking and drinking can lower vitamin levels and potentially trigger early hair loss, but overall vitamin levels don't seem to affect hair loss duration.

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.

Finasteride treats enlarged prostate, shrinks it, improves urination, but may cause sexual dysfunction and isn't for women or children.

Androgens play a complex role in skin conditions like acne and hair loss in women, and normal blood levels don't always show true androgen status.

Male tissue has more cell death than female tissue after ischemia, and some neurosteroids only protect female cells.

Erythropoietin overexpression disrupts hair growth and fat formation in mice.

Bioengineering can potentially treat hair loss by regenerating hair follicles and cloning hair, but the process is complex and needs more research.

The exact cause of increased 5α-reductase activity leading to hirsutism in women is still unknown.

Diabetes causes lasting cell dysfunctions, leading to serious complications even after blood sugar is controlled.

Zinc deficiency disrupts hair growth and cycle, but zinc supplements can fix this.

Androgen is important in controlling stem cell differentiation, reducing fat development, and increasing lean mass.

A new plant extract from Avicennia marina could potentially be used to treat common hair loss.

Leptin helps start the growth phase of hair.

High glucocorticoids cause pancreatic malfunction and malabsorption, reversible with enzyme supplements.

The Notch signaling pathway helps in mouse hair development through a noncanonical mechanism that does not rely on RBPj or transcription.

SA linked to mitochondrial issues and oxidative stress, while AGA involves disrupted hair growth genes.

Finasteride affects offspring's antioxidant enzymes in epididymis, possibly disrupting sperm maturation.

Fzd2 is important for skin and hair development through various signaling ways.

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.

The created skin model with melanoblasts improves the study of skin color and offers an alternative to animal testing.

Hair loss in androgenetic alopecia is caused by genetic factors and androgen excess, and can be treated with combined therapies.

Smart biomaterials that guide tissue repair are key for future medical treatments.

Androgenetic alopecia involves genetics, hormones, and can be treated with medications or surgery.

Platelet-Rich Plasma (PRP) increases the number of new hair follicles and speeds up hair formation.

The document concludes that understanding hair and feather regeneration can help develop new regenerative medicine strategies.

Some patients developed skin inflammation after obesity surgery, and a medication called dapsone helped treat it.
