Male and female skin differ due to hormones, affecting conditions like hair loss, acne, and skin cancer, and suggesting a need for gender-specific treatments.

Superficial granulomatous pyoderma is a unique, mild form of skin disease that often heals without strong medication and responds well to milder treatments.

Humans lost body hair relatively recently in evolution.

Nanoparticles improve drug delivery through the skin but more research is needed on their long-term effects and skin penetration challenges.

Alopecia areata causes hair loss, has no cure, and various treatments exist.

Guidelines for diagnosing common hair loss include detailed history, clinical examination, and various diagnostic techniques.

Bioprinting could improve wound healing but needs more development to match real skin.

Stem cell self-renewal is complex and needs more research for full understanding.

Pig skin is a good substitute for human skin to measure drug absorption, but differences in skin structure and enzymes across species must be considered.

Researchers developed promising agents for prostate cancer imaging, with the best one showing high potential for clinical use.

The document concludes that accurate diagnosis of ichthyosis is crucial for treatment and genetic advice, and ongoing research is needed for better therapies.

Cathepsin L is essential for normal hair growth and development.

Lupus affects the body and skin, causing joint pain and skin issues that can be treated with steroids and antimalarial drugs.

Young adults have about 230,000 tactile nerve fibers, decreasing 5-8% per decade with age.

Hair follicles may soon be used more for targeted and systemic drug delivery.

Estrogen replacement can improve skin health in menopausal women but doesn't reverse sun damage or prevent hair loss.

Different types of stem cells with unique roles exist in blood, skin, and intestines, and this variety is important for tissue repair.

Estrogen loss during menopause worsens skin health, but hormone replacement therapy may improve it, though more research is needed.

Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.

Antibiotics can reduce acne but may lead to resistant bacteria, and understanding the skin's bacteria is important for treatment.

Human dermal fibroblasts are the main cells targeted by a virus that can cause a deadly skin cancer, and a certain inhibitor can effectively block this infection.

Fat-derived stem cells show promise for skin repair and reducing aging signs but need more research for consistent results.

Electrolysis is effective for permanent hair removal, but technique is key to avoid scarring, and sometimes hormonal treatment is needed for women with hirsutism.

Nanoparticles can improve skin drug delivery but have challenges like toxicity and stability that need more research.

Estrogen Receptor ß (ERß) is the main hormone controller in human skin and hair follicles, not Estrogen Receptor α (ERα) or the Androgen Receptor (AR).

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.

Obesity is linked to various skin problems and may increase the risk of skin cancer.

Prolactin contributes to hair loss by promoting hair follicle shrinkage and cell death.

The skin's internal clock affects healing, cancer risk, aging, immunity, and hair growth, and disruptions can harm skin health.

Mice hair growth patterns get more complex with age and can change with events like pregnancy or injury.
