HB 1135 Colorado House · 2026 Regular Session

Transparency of Chemicals Used in Hair Products

Summary
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.)
