Systems, methods, and devices are presented for treating a tissue site and managing hair proximate the tissue site. A composition is provided for inhibiting, removing, or weakening hair proximate the tissue site and for providing an improved fluid seal by a flexible film drape over the tissue site.
Systems, methods, and devices are presented for treating a tissue site and managing hair proximate the tissue site. A composition is provided for inhibiting, removing, or weakening hair proximate the tissue site and for providing an improved fluid seal by a flexible film drape over the tissue site. In some example embodiments, a hair-modification agent is disposed at least proximate a peripheral edge of a treatment manifold between a drape and epidermis proximate a tissue site. The hair-modification agent can be configured to flow over imperfections on the epidermis and to form a fluid seal against the epidermis, and can further be configured to at least substantially weaken hair on the epidermis as the hair encounters the hair-modification agent.
