L.001

HOU Business Affairs & Labor

Passed [*]

Plain English: The amendment changes how violations of the Hair Product Transparency and Safety Act are treated, making them a deceptive trade practice instead of a civil penalty.

Changes 'civil penalties' to 'deceptive trade practice' in the bill's text.
Adds new section (1)(qqqq) to Colorado Revised Statutes 6-1-105, which defines violating Section 25-5-429 as a deceptive trade practice.

The amendment references Section 25-5-429, but does not provide its content, so the exact nature of what constitutes a violation is unclear without additional context.

L.002

HOU Business Affairs & Labor

Passed [*]

Plain English: The amendment adds definitions for 'intentionally added' chemicals and their incidental presence in hair products.

Defines what it means for a chemical to be 'intentionally added' to a covered hair product, specifying that it must remain above certain concentration levels or health thresholds set by relevant entities.
Clarifies that 'incidental presence' refers to the unintentional inclusion of chemicals during manufacturing processes.
Replaces references to carcinogens and reproductive toxicants with 'intentionally added carcinogens and intentionally added reproductive toxicants'.

The amendment text does not provide specific details on how health thresholds are identified or by which entities.

L.003

Passed [*]

Plain English: The amendment removes the word 'synthetic' from certain definitions in the bill and adds a new definition for hairpiece products.

The exact impact of removing 'synthetic' from the definitions is not fully explained in the amendment text.

L.004

SEN Business, Labor, & Technology

Passed [*]

Plain English: The amendment adds requirements for warning labels on hair products to be consistent and align with federal standards, allows the Attorney General to update these rules starting July 1, 2028, and excludes certain professional-use products from the label requirement.

Inserts language allowing the Attorney General to update the warning label requirements starting July 1, 2028.

The exact nature of future updates by the Attorney General is not specified and may depend on federal guidance at that time.

SECTION 1. Legislative declaration. (1) The general assembly2
finds that Coloradans deserve access to personal care products that are3
safe, advertised transparently, and free from hidden health risks.4

including hair relaxers and hairpieces, are disproportionately6
marketed to and used by communities that have historically faced7
elevated exposure to harmful chemicals and related health disparities.8
(3) The general assembly further finds that consistency in warning9
label requirements for similar products benefits both consumers and10
manufacturers by promoting clarity and reducing unnecessary burdens. In11
developing these requirements, it is the intent of the general assembly that12
Colorado establish its own requirements that:13
(a) Meet or exceed comparable consumer protection standards;14
and15
(b) Align with applicable federal law and guidance, including new16
or updated classifications of the International Agency for Research on17
Cancer established by the World Health Organization, the secretary of the18

encourage safer product formulation by ensuring clear and consistent1
disclosure when hair relaxer products and hairpiece products contain2
chemicals known to cause cancer or reproductive harm.3
