Punch Biopsy is a diagnostic procedure used in dermatology and hair restoration to extract a small section of scalp tissue. This method provides valuable insights into the underlying causes of hair loss or scalp conditions, aiding in the development of targeted treatment plans.

The procedure involves using a circular blade, typically 2–4 mm in diameter, to remove a core of tissue that includes the skin and underlying structures. The sample is then analyzed under a microscope to identify issues such as inflammation, scarring, or follicular abnormalities.

Punch biopsies are particularly useful for diagnosing conditions like alopecia areata, scarring alopecia, and other forms of hair loss that require a detailed understanding of scalp health. The procedure is performed under local anesthesia and is minimally invasive, with a quick recovery time.

Patients benefit from the precise diagnostic capabilities of punch biopsies, which ensure accurate diagnosis and effective treatment. This procedure plays a critical role in addressing hair loss at its root cause, leading to more effective and personalized solutions.
