Skin stem cells help repair damage and maintain healthy skin.

Hair follicles help absorb and store topical compounds, aiding targeted drug delivery.

Noggin is necessary to start the hair growth phase in skin after birth.

Lactate production is important for activating hair growth stem cells.

A new microneedle patch made from hair proteins helps regrow hair faster and better than current treatments.

Metformin is effective for treating excessive hair growth in women with PCOS and may work better than the standard treatment in some ways.

The 2003 guidelines suggest that while some treatments can regrow hair in alopecia areata, none alter the disease's progression, and wigs may be the best option for extensive hair loss.

Menopause can lead to skin and hair problems due to hormonal changes, but hormone replacement therapy might help slow these effects.

Alopecia areata involves immune activation in the scalp, suggesting treatments targeting TH1, TH2, and IL-23 pathways.

Macrophages help activate hair follicle stem cells, affecting hair growth and skin repair.

A substance called DKK-1 increases in balding areas and causes hair cells to die when exposed to DHT.

Epidermal stem cells are diverse and vary in activity, playing key roles in skin maintenance and repair.

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.

Follicular Unit Extraction (FUE) is a less invasive hair transplant method with minimal scarring, suitable for about 60% of patients, especially those needing fewer grafts and quicker recovery.

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

Laser hair removal effectiveness depends on targeting hair structures without harming the skin, and improvements require more research and expert collaboration.

Alopecia areata is an autoimmune disease causing patchy hair loss, often with other autoimmune disorders, but its exact causes are unknown.

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.

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

EGFR inhibitors often cause skin problems and other side effects, but these are usually reversible and can be managed to keep patients comfortable.

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

The HR protein helps hair grow by blocking a hair growth inhibitor, aiding in hair follicle regeneration.

Stem cell therapy, particularly using certain types of cells, shows promise for treating hair loss by stimulating hair growth and development, but more extensive trials are needed to confirm these findings.

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

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

Minoxidil can help grow hair in mice by making cells grow and improving hair quality. More research needed.

The telogen phase of hair growth is active and important for preparing hair follicles for regeneration, not just a resting stage.

Understanding how cells die in the skin is important for treating skin diseases and preventing hair loss.

MIM is crucial for hair follicle formation and regeneration by controlling cilia formation and hedgehog signaling through its interaction with Cortactin and Src.
