Make the photos
comparable.
Hair changes slowly. Camera conditions change instantly. Use these tools to remove some of the noise before you decide whether anything actually looks different.
A small lab for better progress photos.
No pseudo-diagnosis and no AI score telling you your hair is “12% better.” Just tools that make the underlying record more consistent and easier to inspect.
Comparison Studio
Align two photos manually, then inspect them with a split slider or transparency overlay.
Open comparator ↗A/BPhoto Consistency Audit
Compare average brightness, contrast, orientation, and image geometry before trusting a before/after.
Audit a pair ↗±Contact Sheet
Turn several dated progress photos into one downloadable timeline image.
Build one ↗Framing Reference
Add simple thirds, centerline, and crop guides to a baseline photo for your next session.
Make reference ↗Private Check-in Log
Keep dates, haircut notes, and setup changes locally on this device; export when needed.
Open log ↗Photo Protocol
A concise one-screen checklist for repeatable hair photos. Save it instead of reading another essay.
View checklist ↗Research that starts with the question.
The library covers both the mechanics of measuring progress and evidence-grounded treatment questions. Comparison pages show the sources they rely on instead of asking you to trust a black-box score.
Compare options without pretending there is one universal winner.
Evidence, regulatory context, tradeoffs, limitations, and what the available studies can — and cannot — tell you.
Treatments, guides, and source-grounded answers.
Medical-adjacent pages are researched against PubMed and current U.S. labeling data, then run through a separate evidence editor before publication.
Want the routine handled for you?
Baldwin keeps the baseline, repeatable check-ins, treatment context, and comparisons in one timeline. The web tools are free; the app is for people who want the system to persist.
