A second domain of high sulfur KAP genes on chromosome 21q23 is crucial for hair structure.

Loose anagen hair syndrome is caused by structural abnormalities in the hair follicle's inner root sheath.

The research found two types of calcium in human hair, one that varies among individuals and another that is consistent across people.

Pollution exposure speeds up hair damage.

Hair's strength and flexibility come from its protein structure and molecular interactions.

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

Micrografts promote hair growth in androgenetic alopecia treatment.

The study found that a polymer treatment changes the charge on hair surfaces, making bleached hair smoother and less porous.

Melanin density affects hair color, and this method can help in cosmetic assessments and diagnosing hair diseases.

Hair's internal fibers are arranged in a pattern that doesn't let much water in, and treatments like oils and heat change how much water hair can absorb.

Teratoma hair is similar to scalp hair but has a rougher surface and lower adhesive force.

Hair is a complex organ, and understanding its detailed structure and growth phases is crucial for analyzing substances within it.

Hairless mammals have genetic changes in both their protein-coding and regulatory sequences related to hair.

The document explains how hair is studied in forensics to identify its source and its role in criminal investigations.

Microfluorometry effectively measures how much polymer coats and penetrates hair, useful for evaluating hair products.

Understanding hair surface properties is key for effective hair care products.

Environmental, chemical, mechanical, and personal health factors can all damage hair and contribute to hair loss or changes in hair quality.

Hair analysis for drugs needs a better understanding of how drugs enter hair, considering factors like hair structure and pigmentation.

Human hair has a protective lipid layer that can be damaged by moisture and treatments, affecting hair growth and health.

Monotreme hair structure and protein distribution are similar to other mammals, but their inner root sheath cornifies differently, suggesting a unique evolution from reptile skin.

Involucrin helps strengthen the inner parts of human hair.

Healthy scalp leads to better hair quality and less damage.

A small molecule can strengthen fine hair, making it more resistant and natural-feeling.

Hairlessness in mammals is due to complex genetic changes in both genes and regulatory regions.

Rare changes in the KRT82 gene are linked to a higher risk of Alopecia Areata.

The document concludes that understanding the genes and pathways involved in hair growth is crucial for developing treatments for hair diseases.

Calcium reduces involucrin in rat hair bulbs but doesn't affect filaggrin and Kdap.

Epidermal stem cells are diverse and vary in activity, playing key roles in skin maintenance and repair.

Androgens can cause hair growth in some areas and hair loss on the scalp.

Testosterone and dihydrotestosterone affect hair growth, and new techniques like the folliculogram help study it, but fully understanding hair growth is still complex.
