The direction in which the hair cuticle lies and its importance when disentangling wet hair?

The hair cuticle lies downwards when u shampoo it opens up the cuticle and when u condition it closes the cuticle. It is not good to use petrissage with long hair as it will tangle the hair. when detangling the hair the hair cuticle helps the hair detangle easier as the hair will be soft. u must use a wide tooth comb to detangle the hair.
