How to Take a Clear Lice Check Photo for Better AI Triage
Photo quality is the biggest controllable factor in AI lice screening. A clear, well-lit close-up near the scalp helps the model interpret evidence and reduces unnecessary uncertainty.

What makes a photo useful for AI
The checker needs to see scalp and hair roots clearly. Casual snapshots from a distance rarely provide enough detail for confident triage.
Focus on one section at a time with hair parted in a straight line. Multiple angles across the nape and behind the ears often improve interpretation.
Lighting and parting technique
Use strong, even light aimed at the scalp rather than directly into the camera lens. Natural daylight or a bright lamp works well.
Part hair with a comb so roots are visible. Avoid shadows across the part line, which can hide attached particles.
Angles and distance that work best
Hold the phone 10–20 cm from the scalp and tap to focus on the roots. Take at least two shots from different zones.
Prioritize the nape, crown line, and areas behind the ears where lice and nits are often first noticed.
Common photo mistakes to avoid
Blur from movement, flash glare, and wet hair reflections are frequent causes of low-confidence results.
Avoid heavy filters, extreme zoom, or photos taken through bathroom steam.
How to review before uploading
Zoom in on your photo: can you see individual strands near the scalp? If not, retake before scanning.
If quality looks borderline, run a manual comb check in parallel rather than relying on a single poor image.
Frequently asked questions
Does one perfect photo guarantee detection?
No. Even good photos are indicative only. Repeat checks and professional confirmation remain important when symptoms persist.
What minimum size does the checker require?
The shortest side should be at least 640 pixels. Smaller images are rejected before analysis.
Should I wet the hair first?
Dry or damp conditioned hair is usually easier to part. Very wet hair can create glare that reduces photo quality.
Ready for a quick next step?
Start a free photo scan first, then use the clinic finder if you want professional confirmation.
