Taxonomy for the assessment of the subjective experience of curly hair manageability

Objectives
This paper aims to develop and validate a taxonomy for the assessment of the subjective experience of curly hair manageability. It represents the latter of two iterative stages of a mixed-method design interdisciplinary project.

Methods
The qualitative stage of the study incorporated thematic analysis of 14 interview transcripts generated using a video-ethnographic method (SEBE). A survey-based instrument assessing different elements of the construct of hair manageability designed during the first stage of this project was further developed following consultations with experts with extensive experience in hair research, product development, testing and trichology. The instrument was tested online with 506 female participants self-reporting natural curly hair, types 3A and higher according to the Andre Walker Curl Classification.

Results
The initial construct of four groups of hair goals received positive content validity from the experts. High scale reliability was achieved for the aesthetic, haptic and emotive goals' scales as well as for hair esteem (Cronbach's alpha >0.75). Curl type was the only personal hair attribute that was correlated with hair goals and perceptions. From the demographic and lifestyle data, only age was correlated with goals and willingness to try new products. Common hair practices and product usage were also correlated with hair curl and goals.

Conclusion
The appropriateness of the instrument for measuring the strength of different hair goals and perceptions relevant to hair curvature degree and hair esteem has been validated. The instrument will support the development and testing of products better aligned with the manageability needs of very curly and textured hair. It was also confirmed that hair curvature is the most significant determinant of practices, and age of product attitudes.
