Estrogen loss during menopause worsens skin health, but hormone replacement therapy may improve it, though more research is needed.

Turmeric may have benefits for skin health, but more research is needed to confirm its effectiveness.

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

Adam10 enzyme is crucial for healthy skin and proper Notch signaling.

Human dermal fibroblasts are the main cells targeted by a virus that can cause a deadly skin cancer, and a certain inhibitor can effectively block this infection.

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

Fat-derived stem cells show promise for skin repair and reducing aging signs but need more research for consistent results.

TGF-β signaling is crucial for stem cell maintenance, differentiation, and has implications for cancer treatment.

Skin grafts on mice can cause an immune response leading to hair loss, useful for studying human hair loss conditions.

Allergic reactions to blood thinners are rare but can be serious, requiring careful testing and alternative treatments.

Estrogen Receptor ß (ERß) is the main hormone controller in human skin and hair follicles, not Estrogen Receptor α (ERα) or the Androgen Receptor (AR).

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.

Damage to skin releases dsRNA, which activates TLR3 and helps in skin and hair follicle regeneration.

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

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

Probiotic bacteria improved skin and hair health in aged mice.

Low doses of some substances can be beneficial, while high doses can be harmful or toxic.

Normal skin cell renewal doesn't need RAR signaling, but vitamin A-related skin thickening does.

Oxidative stress contributes to hair graying and loss as we age.

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

Foxp3 is crucial for regulatory T cell function, and targeting these cells may help treat immune disorders.

Stress can cause hair loss by negatively affecting hair follicles and this effect might be reversed with specific treatments.

Fat cells in the skin help start healing and form important repair cells after injury.

Testosterone's muscle-building effects do not require its conversion to DHT.

New targets for making and using brain-synthesized steroids could lead to better treatments for brain disorders and alcoholism.

Male pattern baldness involves hormones and cell signals affecting hair growth.

Hair follicles produce and respond to melatonin, affecting hair growth and sensitivity to estrogen.

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

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

Cytokeratin 19 and cytokeratin 15 are key markers for monitoring the quality and self-renewing potential of engineered skin.
