What zones this covers
This protocol focuses on: overall, hairline, temples, crown. Track zones separately so you do not average away the signal.
Why this matters
- Switching formats without a baseline makes it impossible to know what changed.
- A single-variable approach reduces regret and prevents endless tinkering.
What to photograph
- Baseline week 0 photos (hairline/temples/crown).
- Weekly photos with the same setup during any switch window.
What to log
- Exact switch date and what changed (only one variable if possible).
- Adherence and side-effect questions to discuss with a clinician.
- Haircuts/styling changes and stress/illness timeline.
How to interpret what you see
- Treat the week of a switch as a new baseline for comparisons.
- Compare 4-8 week windows and avoid interpreting single weeks.
Decision points (when to wait vs act)
- Baseline first, then decide with a clinician if switching is appropriate.
- Do not stack changes during the switch window.
- Reassess direction after multiple consistent windows.
When to get evaluated
- Any medication questions or concerning symptoms should be discussed with a clinician.
- Sudden shedding with scalp symptoms warrants evaluation.
Common mistakes that fake progress
- Switching and adding new products simultaneously.
- Comparing photos across different hair lengths.
- Changing lighting/angle and interpreting noise as results.
FAQ
How long should I wait before judging a switch?
Use multi-week windows. Compare 4-8 week trends with the same setup rather than reacting to single photos.
