Punch Biopsy: Hair Removal Requirements

Hair Management for Scalp Punch Biopsy

No, the entire scalp is not shaved. Only a tiny patch (2–4 mm) of hair directly at the biopsy site is trimmed or shaved to allow sterile prep and clear access for the punch instrument (typically 3–6 mm diameter).

Procedure Details

• Local anesthetic injected.
• Small area clipped/shaved (often with disposable razor or scissors).
• Skin prepped (chlorhexidine/alcohol).
• Punch tool rotated to obtain core specimen.
• Hemostasis (pressure, cautery, suture if needed).
• Hair regrows normally; no cosmetic deficit.

Patient Reassurance

Emphasize minimal hair removal; no full shave required. Cosmetic result negligible.
