Hair and Hair Care Terminology

Furuncle: Acute bacterial infection of a hair follicle, commonly known as a boil, which causes persistent pain.
End Bonds: Another term for peptide bonds, essential in the structure of proteins.
Disulfide Bonds: Bonds that are reformed using thio neutralizers during hair treatments or chemical processes.
Whorl: A hair pattern characterized by circular formations on the crown of the head, influencing hairstyle choices.
Keratinization: The process by which hair matures, involving the conversion of cells to keratin, essential for hair strength and texture.
Scabies: A skin condition caused by a mite burrowing under the skin, leading to severe itching and irritation.
Peptide Bonds: Connections formed between amino acids, critical in protein synthesis, including keratin in hair.
Trichology: The scientific discipline focused on hair health, its diseases, and appropriate care methods.
Hair Composition: A mature strand of hair consists of two main parts: the hair root (below the surface) and the hair shaft (visible part).
Ringed Hair: Hair strands exhibiting bands of alternating pigmented and grey hair, creating a striped appearance throughout.
Pheomelanin: The pigment responsible for red to blond hair colors, influencing hair color diversity.
Telogen Phase: The final stage in the hair growth cycle, where fully grown hair is maintained until it is eventually shed.
Hair Cuticle: The outermost layer of hair composed of transparent, scale-like cells, playing a crucial role in hair protection and shine.
Types of Side Bonds: Three different types of side bonds cross-link polypeptide chains in hair, establishing structural integrity and stability.
Coarse Hair: Characterized by the largest diameter among hair types, often requiring more extensive processing during treatments.
