The important points
- Hair grows slowly, so treatment is assessed over months rather than days.
- Temporary shedding can occur after starting some treatments.
- Use the same light, distance, angle and hairstyle for progress photographs.
- No response should trigger a review—not unsupervised dose escalation.
Hair growth does not change overnight
Follicles move through growth and resting phases. A treatment may be biologically active before a visible cosmetic change becomes obvious. Looking in the mirror every day introduces lighting and styling differences that can exaggerate normal variation.
A practical photography protocol
Take front, both temple, top and crown photographs in the same room, at the same distance, with dry hair and similar hair length. Label the date and avoid filters. A baseline and follow-up set is more valuable than dozens of inconsistent images.
| Point | Clinical meaning |
|---|---|
| Baseline | Record pattern, density, scalp symptoms and current treatment. |
| Early phase | Focus on correct use and tolerance rather than immediate cosmetic change. |
| Three to six months | Compare standardised photographs and discuss adherence and adverse effects. |
| Longer term | Continue, modify or stop treatment according to benefit, tolerance and clinical advice. |
When to review
The agreed review point depends on the diagnosis and treatment. Earlier contact is appropriate for concerning adverse effects, rapid worsening, scalp inflammation or new symptoms. Lack of visible benefit after an adequate trial should prompt reassessment of diagnosis, technique, adherence and alternatives.
