Engineered skin substitutes can grow hair but have limitations like missing sebaceous glands and hair not breaking through the skin naturally.

The conclusion is that measuring how drugs partition into artificial sebum is important for predicting their delivery into hair and sebaceous follicles, and it provides better information than traditional methods.

Liposomes can make the antiandrogen RU 58841 more effective for skin application by reducing absorption, increasing skin retention, and targeting sebaceous structures.

Matriptase is highly active in hair follicles and sebaceous glands, especially during hair growth phases.

Aging skin shows thinner layers, fewer hair follicles, and new biomarkers like increased space between cells and smaller sebaceous glands.

The main difference in hair loss for lupus patients is smaller and fewer sebaceous glands.

Horse skin has a layered epidermis, a dermis with hair follicles, sweat and sebaceous glands, and is supplied by small arteries.

Sebaceous glands play a key role in skin health and conditions like acne.

The sebaceous gland plays a significant role in hair loss and thinning, and using growth stimulators, DHT inhibitors, anti-inflammatory drugs, anti-androgens, and super oxide dismuse substances can help manage it.

Green tea extract increases lipid production in human sebaceous gland cells.

Hair can regrow if the sebaceous gland is intact, even if the hair root is removed.

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.

We now understand more about what causes acne and this could lead to better, more personalized treatments.

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.

Creating stronger blockers for skin enzymes might lead to better treatment for conditions like acne and excessive hair growth.

Insulin resistance and obesity are key factors in the development and worsening of polycystic ovary syndrome, and lifestyle changes are important for managing it.

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.

The hedgehog signalling pathway is key in skin development and basal cell carcinoma, offering insights for prevention and treatment.

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.

Dermatoscopy and videodermatoscopy are useful for diagnosing and monitoring various skin, hair, and nail conditions.

Different types of stem cells in hair follicles play unique roles in wound healing and hair growth, with some stem cells not originating from existing hair follicles but from non-hair follicle cells. WNT signaling and the Lhx2 factor are key in creating new hair follicles.

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.
