Hair follicle dermal stem cells are key for regenerating parts of the hair follicle and determining hair type.

Researchers found specific genes in the part of hair follicles that could help treat hair disorders.

The research found that postmortem root bands in hair are likely caused by the breakdown of a specific part of the hair's inner structure after death.

The conclusion is that future hair loss treatments should target the root causes of hair thinning, not just promote hair growth.

Prolactin affects hair growth cycles and can cause early hair follicle regression.

Wool follicles are complex, involving interactions between different cell types and structures.

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

Hair is a complex organ, and understanding its detailed structure and growth phases is crucial for analyzing substances within it.

All-trans retinoic acid causes hair loss by increasing TGF-β2 in hair follicle cells.

The document concludes that specific cells are essential for hair growth and more research is needed to understand how to maintain their hair-inducing properties.

Hair follicle stem cells and skin cells show promise for hair and skin therapies but need more research for clinical use.

The study created a new model to better understand human hair growth and health.

Transplanted transected hair follicles can survive but grow at unsatisfactory rates and are thinner, suggesting limited potential for unlimited donor hair supply.

Cutting hair follicles into pieces for transplantation results in poor growth and thinner hair, and the technique is more invasive than previously thought.

UVB radiation harms hair growth and health, causing cell death and other changes in human hair follicles.

Human hair follicles can make and process prostaglandins, which may affect hair growth.

Psychotropic drugs can cause hair loss or excessive hair growth.

Hair growth can be stimulated by combining certain skin cells, which can rejuvenate old cells and cause them to specialize in hair follicle creation.

Dermal cells are key in controlling hair growth and could potentially be used in hair loss treatments, but more research is needed to improve hair regeneration methods.

Hair is important for protection, social interaction, and temperature control, and is made of a growth cycle-influenced follicle and a complex shaft.

Fat under the skin releases HGF which helps hair grow and gain color.

The review concludes that accurate diagnosis of different types of hair loss requires proper biopsy techniques and understanding the hair growth cycle and underlying causes.

The protein CCN2 controls hair growth by affecting hair follicle formation and stem cell activity in mice.

HIV-1 may cause increased stem cell death in hair follicles, leading to hair loss.

Hair growth is influenced by hormones and goes through different phases; androgens can both promote and inhibit hair growth depending on the body area.

Loose Anagen Hair Syndrome is a hereditary condition causing hair loss in children due to abnormal hair follicles.

The document concludes that the trichogram is a useful tool for diagnosing hair loss and suggests semi-organ cultures for practical trichological research.

More dermal papilla cells in hair follicles lead to larger, healthier hair, while fewer cells cause hair thinning and loss.

The hair follicle infundibulum plays a key role in skin health and disease, and understanding it better could lead to new skin disease treatments.

TPA promotes hair growth by increasing stem cell activity and activating specific cell signals.
