Zero-waste solid shampoo/conditioner/serum bars; plastic- and silicone-free; carbon-neutral; described as one of Sephora's most sustainable brands.
| Ingredient transparency | Could not be retrieved (no readable product feed, or requests blocked) |
| Ownership | Superzero was founded in 2020 by beauty industry executive Conny Wittke, former CEO of Tweezerman, together with co-founder Gurval Caer, and operated as an independent, venture backed company based in New York. No acquiring parent company was found in any record checked. |
| Price | Mid-range |
| Cruelty free | Yes |
| Vegan | Yes |
| Organic | Partial |
| Certifications | No certification was confirmed on any register checked. PETA's Beauty Without Bunnies database has no entry for Superzero. Leaping Bunny's own brand search tool, confirmed working with positive control searches for other brands, returns zero results for Superzero. Change Climate's certified brand list has no entry for the name either. The brand's own retail description (via Sephora and other stockists) describes the products as vegan and climate neutral, but these are retailer or brand claims, not verified certifications. |
| Packaging | Plastic-free solid bars |
| External ratings | Climate Neutral Certified; vegan; cruelty-free (self-declared); certified microplastic-free; 100% plastic-free packaging |
| Caveat | Trading status uncertain, likely a dead direct to consumer site. The brand's own website has returned errors on every path since mid 2025 with no 2026 archive captures, while retail listings persist. No entry for the brand exists on the PETA, Leaping Bunny or Climate registers, so its cruelty free and vegan claims are unsubstantiated. |
| Reports note | <p>Independent plastic-free haircare-bar brand. Real sustainability certification: Climate Neutral Certified and certified microplastic-free, ~80-90% lower carbon footprint vs liquid; vegan. Cruelty-free is self-declared (not Leaping Bunny/PETA); no published clinical studies or COAs.</p> |
Claims made for this brand that could not be confirmed in a certifier's own register. A brand website is a claim, not a source.
Cruelty free and vegan claims that circulate for this brand on retailer and blog listings could not be confirmed on any certifier's own register: PETA's database returns no match for Superzero, and a direct, working search of Leaping Bunny's brand register also returns zero results for the name. Neither claim should be published as certified.

Why there is no score: Site could not be read. No verdict is given. Neither a full ingredient read nor a check of the certifications against the certifiers own registers has been completed for this brand, so there is no basis for judging it either way. No score is published. No readable product listing could be found at https://www.superzero.com, so the catalogue could not be enumerated. A manual product by product read has not yet been completed.

This brand's product catalogue could not be retrieved automatically: the site exposes no machine-readable product feed, or blocks automated requests. Ingredients may still be listed on individual product pages. Its formulas are not yet verified here.
We read and categorise every ingredient for brands whose full list is published as readable text. This one could not be read automatically, so its formulas are not yet verified here. A complete ingredient list published in readable text is what makes a clean claim checkable.
