How Hold Actually Works
What a styling product is physically doing to a strand, and why humidity undoes some finishes and not others.
Hold is friction and structure, not glue. A styling product either adds texture to the surface of a strand so neighbouring strands catch on each other, or it sets into a film that resists movement. The first keeps hair flexible; the second keeps it fixed.
Both fail in predictable ways. Texture fails when the hair is weighed down; film fails when it takes on moisture. Knowing which one you are using tells you what will break your style first.
