TLDR Curly hair shape is determined by the hair bulb.
The document discussed the hair follicle as a unique, self-renewing organ composed of epithelial and dermal compartments that interact autonomously. It highlighted the follicle as a model of epithelial and mesenchymal interactions, with each compartment following a specific differentiation pathway regulated by growth factors, cytokines, and hormones. The shape of the hair shaft, including curly hair, was noted to be intrinsically programmed from the bulb.
