Textured Hair, Its Characteristics and Comparison Against Non-Textured Hair
The textured hair is wavy, curly, and coily in its configuration and varies a lot in its properties such as hair diameter, ellipticity, tensile strength, fragility, moisture content, ease of combing, and porosity, as compared to straight hair.
Since textured hair varies significantly in its curliness, it is divided into three major types based upon the wavy/curly or coily configuration of the hair. Type 1 is considered as straight/ non-textured hair, whereas Type 2, 3, and 4 are considered as textured hair.
In this study, hair diameters and ellipticity of Type 1, Type 2, Type 3, and Type 4 were determined and the variability in hair diameter within a single hair fiber and within various types were exposed. The differences in tensile strength and ease of combing of Type 1 and Type 4 hair were discussed.
Different methodologies such as Liquid Retention, and Fiber Sink Test were examined to determine fiber porosity. Additionally, porosities of Type 1 and 4 were compared, and differences in porosity of Curly/coily hair type were examined.
