Study Notes
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.
