Eating vitamin A affects hair growth and health by changing cell signals in mice.

Flightless I protein affects hair growth, with low levels delaying it and high levels increasing hair length in rodents.

New treatments for skin conditions related to the sebaceous gland are being developed based on current research.

Antiandrogens and androgen inhibitors like spironolactone, finasteride, and dutasteride can treat hair loss and skin conditions, but they have risks and side effects, including potential harm to pregnant women and risks of cancer and heart issues. Herbal remedies also have antiandrogenic effects but lack safety validation.

Skin cells produce and activate vitamin D, which regulates skin functions and supports hair growth.

Vitamin D and its receptor regulate skin functions like cell growth, immunity, hair cycle, and tumor prevention.

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

TCDD speeds up skin barrier formation by increasing certain gene expressions.

Mice without the vitamin D receptor gene lose hair due to disrupted hair follicle cycles.

Platelet-rich plasma may help in skin and hair treatments, and with muscle and joint healing, but more research is needed to fully understand its benefits and limitations.

Stress activates a special function of the Vitamin D receptor with the help of c-Jun, which can also prevent cell death.

The document concludes that new treatments are needed to better manage acne and reduce side effects related to current therapies.

Thymosin β4 helps improve skin healing and reduce scarring.

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

Acitretin is effective for severe psoriasis and can be used long-term due to no immunosuppression, but must be carefully monitored for side effects and is not for pregnant women.
