DECISION DESK
OUAI Detox, Metal Detox, or Kérastase Première: which shampoo fits which deposit?
Choose among three current U.S. shampoos for ordinary buildup, a color-service metal question, or damaged fiber plus a calcium-focused repair system.
THE DESK'S CALL
The headline.
Our winner for most U.S. buildup decisions: OUAI Detox — with two specialist exceptions
ON THE RECORD
What keeps the headline honest.
This is an editorial conclusion from the stated context. It is not a claimed product trial, diagnosis, or universal ranking.
Decision change
OUAI wins the broad everyday clarifying job; Metal Detox takes the color-and-metal case, while Kérastase Première takes the narrower damaged-fiber calcium-system case.
Evidence boundary
Strand Report did not run a three-way test of cleansing strength, scalp comfort, color retention, or dry-hair feel.
What could overturn the headline.
THE COUNTER-CASE
- Metal Detox wins when color-service metal exposure is the concrete question; the Première system can fit heavily damaged fiber plus a calcium focus.
- No performance ranking is defensible without a shared protocol.
STILL UNREPORTED
- pH, cleansing strength, deposits, friction, breakage, color retention, and scalp measures are rarely provided with comparable methods.
