What Does Hair Type Mean?
Hair type describes the shape and structure of your hair strands, influenced primarily by follicle shape and genetics. The hair shaft consists of layers including the cortex and medulla, while the follicle shape controls curl tightness.
According to a 2020 National Institutes of Health article, hair structure and follicle morphology significantly impact hair type. Further a 2017 dermatological study confirmed that the follicle’s symmetry strongly correlates with curl pattern.
