The challenge of useful serial photographic documentation of hair loss can be met by using a regimented approach at each photographic session. Patient outcomes that are better documented allow for more informed decisions to be made about the course of therapy by both the physician and the patient.

A bit more text:

The ability to photographically document patient progress is especially useful in recording the subtle changes that a hair loss patient may have between office visits. Serial photography (sequential photographs) can be used by both the physician and the patient to assess these changes. Figures 1A and 1B show the therapeutic benefit a patient has achieved in the vertex area of the scalp from an initial to a 6-month follow-up visit. The physician’s challenge as the photographer is significant: to take photographs that allow for the assessment of change, and not a critique of photographic technique. Variability in technique, including patient preparation, lighting, camera settings, camera to patient registration, film, and processing can all undermine the best intentions of photographic documentation.

High-quality clinical photography can be accomplished in the examination room. With the 35-mm camera equipment you may already have in your office, you can structure a methodic approach for taking reproducible serial photographs. Controlled reproducible serial photographs should read like a time-lapse movie, allowing for only the change in a patient’s condition over time. Clinical researchers studying androgenetic alopecia worldwide use controlled photography for primary and secondary endpoints of protocols to determine the efficacy of therapies.
