Androgens can cause hair growth in some areas and hair loss on the scalp.

Tight junctions are key for skin protection and controlling what gets absorbed or passes through the skin.

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.

Memory T cells in the skin balance staying put and moving into the blood, clustering around hair follicles, and increasing in number after infection.

The dermal papilla is crucial for hair growth and health, and understanding it could lead to new hair loss treatments.

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

Eating less sugar, milk, and saturated fats and more vegetables and fish may help treat and prevent acne.

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

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

Human hair follicle organ culture is a useful model for hair research with potential for studying hair biology and testing treatments.

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.

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

The document concludes that understanding hair structure is key to diagnosing hair abnormalities and recommends gentle hair care for management.

Cepharanthine is a well-tolerated drug with multiple medical uses, including anti-inflammatory and anti-cancer properties.

Smoking harms the skin, causing early aging and increasing cancer risk, but stopping smoking can improve skin health.

Liposomes could improve how skin care products work but are costly and not very stable.

PDGFA/AKT signaling is important for the growth and maintenance of certain skin fat cells.

We need more research to better understand human hair follicle stem cells for improved treatments for hair loss and skin cancer.

MicroRNA-214 is important for skin and hair growth because it affects the Wnt pathway.

Chemotherapy often causes temporary hair loss, which is distressing and needs better treatment and support.

One minoxidil-sensitive potassium channel exists in human hair follicles.

Scientists created stem cells that can grow hair and skin.

The document concludes that adult mammalian skin contains multiple stem cell populations with specific markers, important for understanding skin regeneration and related conditions.

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

EGF makes hair follicles grow longer but stops hair production.

Growth factors are crucial for hair development and could help treat hair diseases.

Minoxidil and finasteride effectively treat hair loss.

Blocking β-catenin in skin cells improves hair growth during wound healing.

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

Keratin 15 is not a reliable sole marker for identifying epidermal stem cells because it's found in various cell types.
