When Skin Grafts Grow Hair on the Tongue: An Unusual Side Effect of Cancer Reconstruction

When a section of skin containing healthy hair follicles is used to rebuild part of the tongue, the follicles continue doing exactly what they’re designed to do: grow hair. Even inside the warm, moist environment of the mouth, those transplanted follicles can stay active, producing strands that surprise patients — and sometimes even the doctors. While it may seem alarming, the phenomenon is harmless and simply reflects how faithfully skin grafts retain their original characteristics.

For those who prefer a smooth surface, treatments such as laser hair removal or electrolysis can permanently disable the follicles. Others choose to leave the area as is, especially if the hair growth is minimal or non-disruptive. Medical specialists emphasize that this unusual outcome is rare, manageable, and a direct result of using natural skin tissue for reconstruction. It’s one more example of how remarkable — and sometimes strange — the human body can be during the healing process.
