New hair can grow from large wounds in mice, but less so as they age, involving reprogramming of skin cells and specific molecular pathways.

Hair follicle regeneration is possible but challenging, especially in humans, due to the need for specific cells and a better understanding of how they signal growth.

Dog skin with hair loss, when transplanted to mice, regrew hair, suggesting the hair loss cause is likely body-wide, not skin-specific.

The document concludes that secondary syphilis cases are increasing and often misdiagnosed, pityriasis rubra pilaris can be distinguished from psoriasis by skin cell features, and different skin layers produce specific components during skin repair.

Up to half of people experience itchy scalp, often due to skin conditions like seborrheic dermatitis or psoriasis, and treatments vary based on the specific cause.

The Polish Dermatological Society recommends personalized treatment for cutaneous lupus, including lifestyle changes, medications, and monitoring, with specific drugs for severe cases.

Plant root hair growth is controlled by the hormone auxin, which affects the production of certain oxygen-related molecules through a specific process.

Certain drugs can cause skin lupus, but stopping the drug usually helps. Vaccines work against smallpox, genital herpes, and a type of human papillomavirus. More frequent light therapy clears psoriasis faster. Certain treatments work for psoriasis and dermatitis. A specific cream effectively treats a type of skin cancer. Low iron levels aren't directly linked to chronic hair loss.

The document concludes that individualized treatments for hair issues are effective, certain hair changes can indicate neurocutaneous diseases, specific lotions improve skin health, laser hair removal works but needs more study on long-term effects, men's cosmetics are diverse, peeling is effective but can have side effects, and facial pigmentation is often due to overactive skin cells.

Involucrin gene expression is controlled by specific proteins and signaling pathways.

Blocking specific proteins can help remove aging cells and might treat age-related diseases and promote hair growth.

The study found that bioengineered hair follicles work when using cells from the same species but have issues when combining human and mouse cells.

A specific protein complex increases the activity of a plant enzyme, but this action is not required for plant root hair growth.

The we/we wal/wal mice have defects in hair growth and skin layer formation, causing hair loss, useful for understanding alopecia.

Hair restoration for East Asians should consider their unique characteristics like head shape, hair thickness, and hair density, and use modified procedures and treatments to minimize scarring and maintain hair density.

The skin's layers protect, sense, and regulate the body's internal balance, but can be prone to cancer.

Hair follicle stem cells are key for hair and skin regeneration, can be reprogrammed, and have potential therapeutic uses, but also carry a risk of cancer.

Adam10 enzyme is crucial for healthy skin and proper Notch signaling.

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

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.

Too much Smad7 can cause serious changes in skin tissues, including problems with hair growth, thymus shrinkage, and eye development issues.

The three estrogen receptor genes are highly expressed in zebrafish neuromasts during development.

Hair growth is influenced by interactions between skin layers, growth factors, and hormones, but the exact mechanisms are not fully understood.

Liposomes can safely and effectively deliver substances to mouse hair follicles, potentially useful for human hair treatments.

Chitosan-decorated polymersomes improve finasteride delivery for hair loss treatment.

BLIMP1 is essential for skin maintenance but not for defining sebaceous gland progenitors.

Eph/ephrin signaling is important for skin cell behavior and could be targeted to treat skin diseases.

Smad4 is important for healthy hair follicles because it helps produce a protein needed for hair to stick together and grow.

α-Tocopheryl acetate is well absorbed through healthy skin.

A specific gene variant causes severe skin issues and increases infection risk, requiring careful medical monitoring.
