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.

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.

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

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

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.

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

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.

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.

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

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

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

Asia has made significant progress in tissue engineering and regenerative medicine, but wider clinical use requires more development.

Animals that change color with the seasons mainly do so in response to daylight changes, but climate change is causing camouflage problems that may require evolutionary changes.

New treatments targeting specific genes show promise for treating keratin disorders.

New micelle solutions greatly improve skin delivery of certain antifungal drugs.

UV radiation can help sterilize wounds and promote healing but requires careful use to avoid damaging cells.

Treating sleep apnea in young obese women with PCOS can improve heart health and insulin sensitivity.

MicroRNA-214 is important for skin and hair growth because it affects the Wnt pathway.

Laminin-511 is crucial for early hair growth and maintaining important hair development signals.

A mother's PPARγ is crucial for preventing harmful milk that can cause inflammation and growth problems in babies.

Mutations in the PADI3 gene are linked to a higher risk of scarring hair loss in women of African descent.

Oxidative stress affects hair loss in men with androgenetic alopecia.

Ozone reacts more with unwashed hair, producing compounds due to scalp oils, which could lower ozone exposure but increase exposure to reaction products.
