Start with a goal, not a brand

What should shampoo bars supplements fix for you?

One goal at a time — every score below is computed against the goal you pick, nothing else.

Browsing shampoo bars supplements without a goal makes no sense — different products do different jobs, and “best” flips depending on which job you're hiring for. These are the 45 health outcomes that matter for this category. Pick yours, and the full evidence-ranked shelf loads for that goal alone.

Nothing is ranked yet — the shelf stays locked until you pick a goal.

No goal, no ranking.

A “best shampoo bars supplement” list without a goal would be marketing, not evidence. Pick what you want to improve and DoseRank scores all 16 products against that goal's trials.

Frequently asked

Each product gets a composite score blending clinical strength, evidence, dose fit, trust and value — computed for the goal you picked, across this category's products. The #1 on the DoseRank tab has the highest composite; the other tabs re-rank the same products by Value, Trust, or Popularity. Placement is never paid.
