A haircut can change visual coverage overnight. If you compare different hair lengths, you will overreact to styling artifacts instead of true progression.
TL;DR
- Track haircut dates as part of your protocol.
- Compare like-for-like length windows only.
- Use fixed camera setup plus haircut context notes.
- Delay high-stakes decisions until post-haircut noise settles.

What to track first
- Log every haircut date and target guard length.
- Capture pre-cut and 7-day post-cut reference photos.
- Keep the same top-down and frontal angles.
- Score confidence level for each session when hair length differs.
Decision checklist
- Are you comparing similar hair lengths?
- Was there a recent cut inside this decision window?
- Do trend changes persist after one full length cycle?
- If uncertain, wait one more window before changing protocol.
Track-first next step
Start with a clean baseline and compare weekly captures in 4-8 week windows before changing your routine. Use the start path if you need the fastest way to build a reliable baseline.
