Keratin-associated proteins have ancient origins and were used for different purposes before being adapted for hair in mammals.

The research shows that a gene called Wnt3 affects hair growth and structure, causing short hair and balding when overactive.

Estrogens significantly influence hair growth by interacting with receptors in hair follicles and may help regulate the hair growth cycle.

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

Human beard hair medulla contains a unique and complex mix of keratins not found in other human tissues.

Androgenetic alopecia involves genetics, hormones, and can be treated with medications or surgery.

Hair growth is influenced by interactions between skin layers, growth factors, and hormones, but the exact mechanisms are not fully understood.

The article explains the genetic causes and symptoms of various hair disorders and highlights the need for more research to find treatments.

Better hair care products are needed to protect against grooming and chemical damage.

Melatonin solution helps treat hair loss in men and women.

The document concludes that understanding hair follicle cell cycles is crucial for hair growth and alopecia research, and recommends specific techniques and future research directions.

Certain molecules in hair change with age and could be used for cosmetic treatments.

Modified keratin binds better to hair, especially bleached hair.

Chemical treatments and daily stresses damage hair, especially the cuticle layer.

Male hormones cause different growth in identical human hair follicles due to their unique epigenetic characteristics.

Human hair has more unsaturated fats inside than on the surface, and certain lipids may help bind the outer and inner layers together.

People with Inflammatory Bowel Disease often lose hair due to stress, medication side effects, or lack of nutrients, and treatment depends on the specific cause.

Keratin-based particles safely improve hair strength, smoothness, and heat protection.

Hair in mammals likely evolved from glandular structures, not scales.

Scientists developed a method to grow human fetal skin and digits in a lab for 3-4 weeks, which could help study skin features and understand genetic interactions in tissue formation.

Mushroom-based scaffolds help heal skin wounds and regrow hair.

Keratin's mechanical properties are influenced by hydrogen bonds and secondary structure, and can be improved with the SPD-2 peptide.

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.

Crossbreeding certain European cattle breeds may cause hair and physical issues in cattle.

Hair analysis can show nutritional status and environmental exposure, with phosphorus being very stable in hair and differences found based on gender and conditions like depression and autism.

Human hair varies widely and should be classified by curl type rather than race.

The new hydrogel is good for wound dressing because it absorbs water quickly, has high porosity, can release drugs, fights bacteria, and helps wounds heal with less scarring.

Male pattern baldness may be caused by factors like poor blood circulation, scalp tension, stress, and hormonal imbalances, but the exact causes are still unclear.
