Dyes can penetrate human skin and hair follicles up to 1.2 mm deep and the sebaceous gland can store dye; Indocyanine Green lotion was made for safe dyeing and monitoring.

Hair follicle stem cells can generate all hair cell types, skin, and sebaceous glands.

Skin stem cells are crucial for maintaining and repairing the skin and hair, using a complex mix of signals to do so.

The document concludes that skin stem cells are important for hair growth and wound healing, and could be used in regenerative medicine.

Human skin makes sexual hormones that affect hair growth, skin health, and healing; too much can cause acne and hair loss, while treatments can manage these conditions.

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

Notch signalling helps skin cells differentiate and prevents tumors.

Eating high-glycemic foods and drinking milk may worsen acne by increasing insulin and IGF-1 levels.

The human sebocyte culture model has improved understanding of oily skin and acne, and how they can be treated.

Isotretinoin is highly effective in treating severe acne, rosacea, and gram-negative folliculitis.

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.

New research suggests that skin cell renewal may not require a special type of cell previously thought to be essential.

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 Smad7 changes skin and hair development by breaking down a protein called β-catenin, leading to more oil glands and fewer hair follicles.

Cathepsin L is essential for normal hair growth and development.

Wounded skin cells can revert to stem cells and help heal.

Skin aging is due to impaired stem cell mobilization or fewer responsive stem cells.

Hair follicles are promising targets for delivering drugs effectively.

Pregnancy can cause skin darkening, varicose veins, more sweating, hair growth, hair loss after birth, nail changes, and gum inflammation.

Vitamin D is important for skin health and may affect conditions like psoriasis and hair loss, but more research is needed to understand its role fully.

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

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

Scientists turned mouse stem cells into skin cells that can grow into skin layers and structures.

The study found that two enzymes linked to hair loss are located in different parts of the scalp, supporting a common treatment's effectiveness.

Pregnancy can cause skin pigmentation, stretch marks, and changes in hair, nails, and sweat glands, with most resolving after birth.

Male pattern baldness involves smaller hair follicles, larger oil glands, and other tissue changes, but not major blood supply issues.

The document concludes that accurate diagnosis of different types of hair loss requires careful examination of hair and scalp tissue, considering both clinical and microscopic features.

The method effectively measures lipid changes and drug effects on skin follicles.

The chemicals 17βC and its methyl ester can block the effects of testosterone on hamster skin but not the effects of DHT.

Mutant mice help researchers understand hair growth and related genetic factors.
