How each score was set
Usability 6.0 /10
From published features and owner comments · not a lab test.
- Published ingredients and specs8.0/10
- Shampoo page gives the full INCI, 10.01 oz / 300 ml, a four-step how-to and suitability for fine, curly and colour-treated hair; no country of manufacture or product-level certificate is listed.
- Price transparency8.0/10
- A $38 price with the 300 ml size is shown openly and the policy publishes free US shipping above $65, though the banner promises it above $80.
- Return window3.0/10
- The refund policy covers only unopened bottles returned within 14 days, with sale items excluded, so a shampoo that has been tried is not refundable.
- Guarantee and defect cover1.0/10
- Nothing in the published terms promises a refund for a bottle that disappoints; only defective or damaged deliveries are addressed.
- Subscription terms10.0/10
- The shampoo is a plain one-time purchase; its product data carries no auto-ship plan, so nothing can be enrolled by default.
