Semi-permanent and demi-permanent are different colour categories. Wella’s professional explanation distinguishes their systems and application characteristics; the names should not be treated as interchangeable instructions.
Make the comparison useful
If you plan to alter purchased hair, give the stylist the exact item and known processing history. Ask which named product and service they propose, what it is intended to change and which supplier guidance supports its use. Do not choose a formula solely because a category sounds temporary or gentle.
Your next step
Keep three lines in the brief: current product and colour; intended change; proposed service awaiting assessment. Confirm the hair supplier’s instructions before proceeding. This page explains a vocabulary distinction, not a recipe or a recommendation to chemically treat a Luxeline item.
Explore current wig options or ask Luxeline about the selected item.
The distinction in the source
Wella describes semi-permanent colour as depositing on the outer surface, while demi-permanent colour works into the outer layer. This is a distinction between colour systems, not a prediction of how long either will last on a particular purchased item. The existing colour and previous processing still matter.
