What are the directioon in which the hair curtile lies when the hair is wet?

When hair is wet, the cuticle, which is the outermost layer of the hair shaft, tends to lie flat against the hair strand. This is due to the water's ability to swell the hair, causing the cuticles to open slightly. As a result, the cuticle scales overlap in a downward direction, typically toward the ends of the hair. This positioning helps minimize friction and damage when hair is wet.
