Did you mean Hair Shape?

Glossary Hair Shape

physical form of individual hair strands

Hair shape refers to the physical form or structure of individual hair strands, which can be straight, wavy, curly, or coily. This shape is primarily determined by the shape of the hair follicle and the distribution of keratin proteins within the hair shaft. For example, round follicles typically produce straight hair, while oval or asymmetrical follicles result in wavy or curly hair.
