Photodynamic therapy for hair removal combines light-based treatment with a photosensitizing agent that is applied to the skin. This agent reacts with light to produce a form of oxygen that destroys hair follicles. PDT is primarily used for areas with thin or fine hair and offers the additional benefit of improving skin texture and treating certain skin conditions simultaneously. It is a specialized approach that requires several sessions for effectiveness and is suitable for clients interested in comprehensive skincare and hair removal solutions.
