Experts agree that PCOS affects women's health in complex ways, but more research is needed to understand and treat it effectively.

The guideline suggests using specific criteria to diagnose PCOS, recommends various treatments for its symptoms, and advises screening for related health issues.

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

Epithelial stem cells are crucial for tissue renewal and repair, and understanding them could improve treatments for damage and cancer.

Hair follicle development is controlled by interactions between skin tissues and specific molecular signals.

Nerve signals are crucial for hair follicle stem cells to become skin stem cells and help in wound healing.

Experts recommend using evidence-based methods to diagnose and treat hirsutism, focusing on symptoms and underlying causes.

Stress can worsen skin and hair conditions by affecting the skin's immune response and hormone levels.

Metformin helps with menstrual cycles and insulin levels in PCOS but is less effective for hair growth, diabetes prevention, and weight loss, and may improve fertility and reduce diabetes risk.

Stem cell niches are crucial for regulating stem cell behavior and tissue health, and their decline can impact aging and cancer.

Lgr5 is a marker for active, self-renewing stem cells in the intestine and skin, important for tissue maintenance.

The conclusion is that certain cell interactions and signals are crucial for hair growth and regeneration.

Certain proteins, Lgr5 and Lgr6, are important markers of adult stem cells and are involved in tissue repair and cancer development.

Apoptosis is essential for human skin development and forming a functional epidermis.

Hair loss and aging are caused by the breakdown of a key protein in hair stem cells.

Hidradenitis suppurativa, a chronic skin disease, can be managed with antibiotics, lifestyle changes, and in severe cases, surgery. Early diagnosis and careful planning are key, and laser treatment can be an efficient solution for mild to severe cases.

Future hair loss treatments should aim to extend hair growth, reactivate resting follicles, reverse shrinkage, and possibly create new follicles, with gene therapy showing promise.

Stem cells are crucial for skin repair and new treatments for chronic wounds.

The document concludes that understanding hair follicle biology can lead to better hair loss treatments.

The conclusion is that proper signaling is crucial for hair growth and development, and errors can lead to cancer or hair loss.

Mice lacking the PPARγ gene in their fat cells had almost no fat tissue, severe metabolic problems, and abnormal development of other fat-related tissues.

Telogen effluvium is a reversible hair loss condition that requires a detailed diagnosis and often resolves on its own.

Sebocytes play a key role in controlling androgen levels in human skin.

Visible light can damage skin and most sunscreens don't block it well; more research is needed on its effects and protection methods.

The hedgehog signaling pathway is crucial for hair growth but not for the initial creation of hair follicles.

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

Hair follicle development and microbes help regulatory T cells gather in newborn skin.

Targeted cancer therapies often cause serious skin problems that need careful management.

Alopecia areata is likely an autoimmune disease with unclear triggers, involving various immune cells and molecules, and currently has no cure.

Hair follicle stem cells use specific chromatin changes to control their growth and differentiation.
