Case name:

Olaplex No. 3 Hair Repair Perfector Butylphenyl Methylpropional (lilial) Class Action

Quebec Superior Court file #:



Since 2020, the Plaintiff purchased 4 bottles of Olaplex No. 3 Hair Repair Perfector for $43.00 each (inclusive of taxes) from Sephora. Each of these bottles contained a dangerous chemical called Butylphenyl Methylpropional (lilial). It was only on February 28, 2022 that Olaplex admitted to always being “aware” of the serious health risks associated to lilial – such as infertility and allergies – but never informed its customers of these risks prior thereto.

These health risks are clearly an “important fact” within the meaning of section 228 of the Consumer Protection Act, which Olaplex failed to inform its customers about. Had the Plaintiff been aware of these health risks, she would have never purchased Olaplex No. 3 Hair Repair Perfector.

Proposed Class:

All consumers who purchased, in Canada, Olaplex No. 3 Hair Repair Perfector containing Butylphenyl Methylpropional (lilial).

Remedies sought for consumers:

This class action seeks the reimbursement of the amounts paid by Class members for their purchases of Olaplex No. 3 Hair Repair Perfector containing Butylphenyl Methylpropional, as well as punitive damages in the amount of $10 million, because Butylphenyl Methylpropional is a dangerous chemical with serious side effects (such as infertility and allergies) which Olaplex and Sephora failed to warn consumers about and which was only recently removed from Olaplex’s products in several countries. In Canada, Sephora continues to sell Olaplex No. 3 containing Butylphenyl Methylpropional.


Pending authorization hearing.
