How does genetics influence hair’s natural porosity?
Hair's natural porosity is shaped by inherited genes influencing cuticle structure and hair shape, which dictate how effectively strands absorb and retain moisture.

How does hair follicle shape influence curl pattern?
Hair follicle shape dictates curl pattern; round follicles yield straight strands, while oval to flattened shapes create waves and coils.

How do internal structures influence curl?
Hair's internal structures, including follicle shape, protein distribution, and genetic variations, fundamentally dictate its curl pattern.
