Healing differences: body hair donor

Where does body hair for a hair transplant come from, and why is it used?

Body hair for transplantation can come from the chest, back, shoulders, abdomen and limbs, and in practice it is reserved for people with extensive loss and limited scalp donor, often in repair cases where previous surgery has depleted the usual sources. It supplements rather than substitutes for scalp donor hair.

How do body hair extraction sites heal after donation?

Body hair extraction sites are small punch sites that generally heal without difficulty, with redness and pinpoint marks fading over weeks to months. Folliculitis and ingrown hairs are recognised risks, particularly on the chest and back, and marks may be more visible in people who scar prominently.

• Marks may be more visible in people who scar prominently
• Larger surface areas are involved than in scalp harvesting

Why does body hair behave differently once transplanted to the scalp?

Transplanted body hair behaves differently because it has a shorter growth phase than scalp hair, so it doesn't reach comparable length, and its texture is often finer or more curved. Yield is lower and less predictable than scalp grafts, cycling is asynchronous, which can make coverage look less uniform, and retention of body-hair traits varies.

• Shorter growth phase. Body hair grows for a shorter period than scalp hair and so does not reach comparable length.
• Different texture. Often finer or more curved.
• Lower and less predictable yield than scalp grafts.
• Asynchronous cycling, which can make coverage look less uniform.
• Variable retention of body-hair characteristics after transplantation.

What should you expect from body hair FUE as a donor source?

Body hair FUE can add usable coverage where nothing else is available, and for the right patient that is worthwhile, but it will not match the length, uniformity or yield of scalp donor hair. A clinic presenting it as equivalent is overselling it; anyone offered it as a primary source should get a second opinion.

How much can be taken, and from where, is the subject of our page on donor supply.
