Eyelash curvature is linked to the thickness of the cuticle layer at the root.
research How Different Is Human Hair? A Critical Appraisal of Global Hair Fibre Characteristics and Properties Towards Defining a More Relevant Framework for Hair Type Classification
Human hair varies widely and should be classified by curl type rather than race.
research Porosity at Different Structural Levels in Human and Yak Belly Hair and Its Effect on Hair Dyeing
Yak belly hair has higher porosity and is less stiff than human hair, making it absorb dye better but less suitable as a direct substitute for hair dyeing.
