Plaiting and twisting hair can temporarily alter the hair structure by stretching and reshaping the strands. This can lead to a smoother appearance and reduced frizz. However, excessive plaiting or twisting can cause damage by weakening the hair shaft and potentially causing breakage over time.
Human hair has no cohesive feature. No projecting edge presents at the outer surface of hair, thus twist can not stay after a certain period of twisting itself. Compare to a protein fiber wool, it has sufficient length and strength but its outline is totally over rounded that is why it can not reffer as a textile fiber.
