Oily roots by day two. Flakes. Buildup. A scalp that never feels right — and no idea which product or habit is causing it. RuutCheck runs the experiment that finds out.
Free, in your browser — no download, no signup needed.

No spam — occasional updates only.
A 5-minute assessment looks at your symptoms, your hair, and your actual routine — and tells you the most likely cause, in plain language.
A day-by-day plan that changes one thing at a time — starting with free routine changes, not products — so you know exactly what made the difference.
Track how many hours your roots stay fresh after washing. Keep what measurably helps. Drop what doesn't. Stop guessing.
Not another product quiz. Most apps end in a shopping cart. RuutCheck often ends with "you probably don't need to buy anything yet." We'd rather earn your trust than a commission.
