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.

Minoxidil helps lower severe blood pressure and promotes hair growth but can have serious side effects and must be used continuously.

Skin issues can indicate immune system problems.

Higher RBP4 levels found in people with two types of hair loss.

The secretions of mesenchymal stem cells could be used for healing without using the cells themselves.

Hair follicles are complex, dynamic mini-organs that help us understand cell growth, death, migration, and differentiation, as well as tissue regeneration and tumor biology.

Rosacea is a skin condition with unclear causes, classified into four subtypes.

Keratins help protect cells, aid in cancer diagnosis, and influence cancer behavior and treatment.

The paper concludes that understanding melanocyte development can help in insights into skin diseases and melanoma diversity.

New effective scar treatments are urgently needed due to the current options' limited success.

Latanoprost can make eyelashes longer, thicker, and darker.

Androgens can cause hair growth in some areas and hair loss on the scalp.

Using CDK inhibitors on rats showed a reduction in chemotherapy-caused hair loss, but later experiments could not repeat these results.

The document concludes that more research is needed to better understand and treat primary cicatricial alopecias, and suggests a possible reclassification based on molecular pathways.

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

Men, especially older ones with health issues like prostate cancer, may have worse COVID-19 outcomes and could benefit from therapies targeting male hormones.

Blocking the Wnt pathway could lead to new treatments for cancer and tissue repair but requires careful development to avoid side effects.

Hair follicles are hormone-sensitive and involved in growth and other functions, with potential for new treatments, but more research is needed.

5α‐reductase isozymes are crucial for prostate development and health, and targeting them can help prevent and treat prostate issues.

The Wnt/β-catenin pathway is important for tissue development and has potential in regenerative medicine, but requires more research for therapeutic use.

Minoxidil and finasteride are effective for male hair loss, minoxidil for female hair loss, and various treatments like corticosteroids work for alopecia areata; treatment should be tailored to the individual.

The document concludes that targeting 5α-reductase, the androgen receptor, and hair growth genes, along with using compounds with anti-androgenic properties, could lead to more effective hair loss treatments.

PRP injections effectively treat hair loss, with positive results in both monthly and every three months treatments.

Using patients' own fat-derived cells to treat alopecia areata significantly improved hair growth and was safe.

Hormones and neuroendocrine factors control hair growth and color, and more research could lead to new hair treatment options.

Hidradenitis suppurativa may be related to hormones and patients often have metabolic disorders; more research is needed to understand this connection.
