Official summary
Official text — shown in English exactly as published by the official source. The official text controls.
On and after July 1, 2027, a manufacturer of a hair relaxer product or a hairpiece product (covered hair product) is prohibited from selling or distributing a covered hair product in the state that contains an intentionally added carcinogen or reproductive toxicant unless the covered hair product has a warning label that notifies the consumer that the covered hair product contains an intentionally added carcinogen or reproductive toxicant, which warning label must comply with certain requirements depending on whether the covered hair product contains an intentionally added carcinogen, an intentionally added reproductive toxicant, or both (warning label requirement). The warning label requirement does not apply to a covered hair product that is sold or distributed to a commercial entity for professional use. On and after July 1, 2028, the attorney general may adopt rules updating the warning label requirement. A violation of the warning label requirement constitutes a deceptive trade practice. (Note: This summary applies to this bill as enacted.)

This record carries a fingerprint of its official content, computed by our data pipeline with the SHA-256 algorithm — a real computation over the record itself, not a badge we award ourselves. Anyone can recompute it from the official source and compare.

What it covers: the record exactly as the official source publishes it — its identifiers (bill number, session, jurisdiction), its official title and long title, its official summary, its status, its sponsors in published order, every recorded action, every recorded vote, and the link to each official text version — assembled in a fixed canonical form described on the How this data works page.
The fingerprint does not cover our retrieval date (the “Data as of” stamp in the source line): re-fetching unchanged official content produces the same fingerprint, while any change to the official content changes it.
If you recompute the fingerprint from the official source and get a different value, one of us is out of date — please report it through the corrections log.
