Follicular Unit Extraction (FUE) is a less invasive hair transplant method with minimal scarring, suitable for about 60% of patients, especially those needing fewer grafts and quicker recovery.

Using CDK inhibitors on rats showed a reduction in chemotherapy-caused hair loss, but later experiments could not repeat these results.

Humans lost body hair relatively recently in evolution.

Alopecia areata causes hair loss, has no cure, and various treatments exist.

Bioprinting could improve wound healing but needs more development to match real skin.

About 2.2% of women with symptoms of high male hormones have a mild form of congenital adrenal hyperplasia, and measuring a specific hormone level can accurately diagnose it.

Laser device increases hair density, safe for treating hair loss in men and women.

Too much Smad7 changes skin and hair development by breaking down a protein called β-catenin, leading to more oil glands and fewer hair follicles.

The Sonic hedgehog pathway is crucial for new hair growth during mouse skin healing.

Aging causes skin stem cells to work less effectively.

Young adults have about 230,000 tactile nerve fibers, decreasing 5-8% per decade with age.

Eczema and fungal infections are the most common skin problems in Japan, with different age groups and genders affected by various conditions.

Male hormones affect COVID-19 severity and certain drugs targeting these hormones could help reduce the risk.

Vitamin D is important for skin health and may affect conditions like psoriasis and hair loss, but more research is needed to understand its role fully.

Masculine facial features may not reliably indicate heritable health, and more research is needed.

Sonic hedgehog signaling is crucial for hair growth and maintaining hair follicle identity.

The HR protein helps hair grow by blocking a hair growth inhibitor, aiding in hair follicle regeneration.

Stem cell therapy, particularly using certain types of cells, shows promise for treating hair loss by stimulating hair growth and development, but more extensive trials are needed to confirm these findings.

Some vitamins and minerals like vitamin D and iron can help with certain types of hair loss, but more research is needed for others.

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.

Macrophages help heal nerves by aiding the maturation of Schwann cells and are important for nerve repair.

Silver nanoparticles coated with substances like PEG showed strong antibacterial effects and improved wound healing when used in hydrogels.

Mouse hair follicle cells briefly grow during the early hair growth phase, showing that these cells are important for starting the hair cycle.

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.

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

Minoxidil shortens baldness from chemotherapy by 50.2 days without significant side effects.

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

Janus kinase inhibitors are promising treatments for autoimmune skin diseases like eczema and psoriasis.
