Texturising
Cutting into the hair to remove bulk and give the ends a piecey, separated look.
Also: texturizing, texture cutting
Texturising, in cutting, means removing some of the hair inside a shape so the ends separate into pieces instead of sitting as a solid block. Stylists do it with point cutting, slide cutting, razor work or thinning scissors. It makes short cuts look messy on purpose and makes thick hair lighter and easier to style. The word is also used for a mild chemical treatment that loosens curls, which is a different thing, called here a chemical texturiser.
