Acne patients' skin, both with and without lesions, shows a strong immune response and higher antimicrobial activity.

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

Hair growth is influenced by various body and external factors, and neighboring hairs communicate to synchronize regeneration.

A specific immune response helps control mite populations on the skin, maintaining healthy hair follicles.

The enzyme CD73 helps control human hair growth and could be targeted to treat hair growth disorders.

Exosomes from fat-derived stem cells can potentially improve hair growth and could be a new treatment for immune-related hair loss.

Cholesterol-related compounds can stop hair growth and cause inflammation in a type of scarring hair loss.

Genetic variants linked to ten skin diseases were found, showing both immune and non-immune factors play a role.

Plucked hairs can be used instead of skin biopsies to study hair traits because they contain specific cells related to hair.

MicroRNAs play a crucial role in skin and hair health, affecting everything from growth to aging, and could potentially be used in treating skin diseases.

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.

Men generally have more severe COVID-19 cases and higher death rates than women due to biological differences.

AP-2α and AP-2β proteins are essential for healthy adult skin and hair.

Aligned membranes improve wound healing by reducing scars and promoting skin regeneration.

Caspase-7 has functions in skin and hair that are not related to cell death.

Microneedles are a promising method for drug delivery, offering efficient and convenient alternatives with fewer side effects.

Microglia, the brain's immune cells, may contribute to Polycystic Ovary Syndrome (PCOS) by altering the female brain's structure and function, with kisspeptin neurons and GABA neurotransmitters also playing a role.

An imbalance between certain immune cells is linked to a chronic skin condition and may be influenced by obesity, smoking, and autoimmune issues.

Aged individuals heal wounds less effectively due to specific immune cell issues.

Men are more likely to get infectious skin diseases, while women are more prone to autoimmune and pigment-related skin conditions, influenced by biological and environmental factors.

Melanocytes are important for skin and hair color and protect the skin from UV damage.

Memory T cells in the skin balance staying put and moving into the blood, clustering around hair follicles, and increasing in number after infection.

The document concludes that for hair and feather growth, it's better to target the environment around stem cells than the cells themselves.

Fish oil improves skin health in people with diabetes and high cholesterol.

Zinc supplementation may help improve treatment outcomes for chronic hepatitis C.

Older skin has higher cancer risk due to inflammation and stem cell issues.

Early detection and intensive treatment of diseases caused by Staphylococcus aureus toxins are crucial for reducing severe health effects.

Stress increases a factor in mice that leads to hair loss, and blocking this factor may prevent it.

An imbalance in gut bacteria is linked to skin immune diseases and may affect their outcomes and related health issues.

Wound healing is greatly affected by the types of bacteria present, which can either help or hinder the process.
