What AI values here
Top men's shampoos split between two needs: medicated formulas that target dandruff, and strengthening products for thinning hair. Most options work across hair types rather than being narrowly specialized.

The verdict
You decide
They agree, we say so. They split, we show you the gap.
Act one
What the machines think.
Three AI models read the category and rank every product. They agree on the very top — and split harder than anywhere else below it.
Model by model?
How each AI ranked it.
All three models open with the same #1 when they agree — below it their lists diverge. Each column is one model's own ranked picks; the lead pick sits a touch larger, and a lone tag marks a product only one model chose. The board below merges them into one machines-only top 10.
