On and after July 1, 2027, a manufacturer of a hair relaxer product or a synthetic hairpiece product (covered hair product) is prohibited from selling or distributing a covered hair product in the state that contains a 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 a an intentionally added carcinogen or reproductive toxicant. The warning label must comply with certain requirements depending on whether the covered hair product contains a an intentionally added carcinogen, a an intentionally added reproductive toxicant, or both.      A manufacturer that violates the prohibition or requirement set forth in the bill is subject to a civil penalty of no more than $10,000 per violation. A violation of the prohibition or requirement set forth in the bill constitutes a deceptive trade practice.(Note: Italicized words indicate new material added to the original summary; dashes through words indicate deletions from the original summary.)(Note: This summary applies to the reengrossed version of this bill as introduced in the second house.)
