Nerve signals are crucial for hair follicle stem cells to become skin stem cells and help in wound healing.

Finasteride and minoxidil are effective for hair loss, but continued research is needed for better treatments.

Hair regeneration needs dynamic cell behavior and mesenchyme presence for stem cell activation.

Insulin resistance is a key factor in polycystic ovary syndrome, but genetics may also contribute.

The ZIP7 gene helps control zinc levels in cells by moving zinc from the Golgi apparatus to the cytoplasm.

Peptide hydrogels heal burn wounds faster and better than standard dressings.

Telogen effluvium is a common type of hair loss that can resolve on its own or become chronic, with treatment depending on early diagnosis.

Different types of stem cells and their environments are key to skin repair and maintenance.

Inflammation may be linked to hair loss, and targeting specific enzymes could help treat it.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

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

Finasteride effectively blocks rat enzymes, but with varying methods and strength.

Treatments for permanent hair loss from scarring aim to stop further loss, not regrow hair, and vary by condition, with partial success common.

Nanoparticles can improve skin treatments by better targeting hair follicles, but more research is needed for advancement.

Iranian veterans exposed to sulfur mustard suffer from long-term skin itching and eye damage, with some risk of skin cancer and ongoing management challenges.

Targeted cancer therapies often cause skin reactions, so dermatologists must manage these effects.

Platelet-rich plasma may have some benefits in dermatology, but there's not enough evidence to widely recommend its use.

Excessive selenium from a supplement caused toxicity but patients recovered with care.

Menopause reduces skin collagen and elasticity, and while estrogen therapy can help, its risks require careful consideration.

Cepharanthine, a Japanese hair loss drug, shows promise as a COVID-19 treatment but needs more testing.

The document explains how the male reproductive system works, its role in making testosterone, and how conditions like obesity can disrupt it, leading to low testosterone and fertility issues.

Msx2 and Foxn1 are both crucial for hair growth and health.

Human hair follicles can make and process prostaglandins, which may affect hair growth.

Applying a specific inhibitor lightens skin and hair color.

Environmental factors at different levels control hair stem cell activity, which could lead to new hair growth and alopecia treatments.

The document suggests that targeting the hormone DHT could be a more effective treatment for prostate cancer than targeting testosterone.

Platelet-rich plasma, taken from a person's own blood, can help rejuvenate skin, stimulate hair growth, and treat hair loss, but more research is needed to confirm its safety and effectiveness.

Burn reconstruction improves with new techniques, materials, and tissue engineering.

Treating cystoid macular oedema in uveitis is difficult and risky.

The document concludes with guidance for doctors on diagnosing and treating hirsutism effectively and safely.
