Women with PCOS often have skin problems like excessive hair, acne, hair loss, and dark patches, which can be treated with hormonal and non-hormonal therapies.

Human hair follicles can regenerate after removal, but with low success rate.

Overexpressing the mineralocorticoid receptor in mouse skin causes skin thinning, early skin barrier development, eye issues, and hair loss.

Cell-based therapies using dermal papilla cells and adipocyte lineage cells show potential for hair regeneration.

Mice without certain skin proteins had abnormal skin and hair development.

Hair follicles on the scalp interact with and respond to the nervous system, influencing their own behavior and growth.

Hormonal treatment is effective for women with acne not helped by usual treatments, especially if they have hormonal imbalances.

Hair follicles are essential for skin health, aiding in hair growth, wound healing, and immune function.

Giving dihydrotachysterol to mother rats caused skin hardening and bone issues in their babies through milk.

α-parvin is necessary for skin and hair growth and for the correct orientation of skin cells.

Hair follicles and deer antlers regenerate similarly through stem cells and are influenced by hormones and growth factors.

Mice without the vitamin D receptor have bone issues and other health problems, suggesting vitamin D is important for preventing various diseases in humans.

Fat-related cells are important for initiating hair growth.

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.

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.

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

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.

Nerves are crucial for the regeneration of various body parts in many animals.

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

The document provides a method to classify human hair growth stages using a model with human scalp on mice, aiming to standardize hair research.
