Case name:
Olaplex No. 3 Hair Repair Perfector Butylphenyl Methylpropional (lilial) Class Action
Quebec Superior Court file #:
500-06-001178-223
What this case was about:
This class action was instituted in relation to the sale of the old formula of Olaplex’s No. 3 Hair Repair Perfector (the “Product”) containing a specific ingredient, butylphenyl methylpropional, (the “Ingredient”) and the launch of a new formula of the same product in 2022 without the Ingredient (the “New Product”).
The Plaintiff alleged that Olaplex and Sephora (the “Defendants”) contravened Quebec’s Consumer Protection Act by concealing an important fact by not disclosing the alleged health risks that could be associated with the presence of the Ingredient in the Product and falsely representing in February 2022 that they had removed the Ingredient from the Product by launching the New Product. These allegations have not been proven in Court and have been, and continue to be, denied in all respects by the Defendants, who say that they have complied with all applicable legislation at all times and deny any health risks associated with the presence of the Ingredient in the Product, before its removal of the New Product’s formula in 2022.
Class authorized for settlement purposes:
All consumers who, with a billing address in Quebec, purchased from the Defendants at least one (1) bottle of Olaplex No. 3 Hair Repair Perfector containing Butylphenyl Methylpropoional (lilial) between March 1, 2019 to August 31, 2022.
Terms of the settlement:
The Settlement provides that the Defendants will offer each Settlement Class Member the possibility of:
(1) receiving a free 100ml bottle of Olaplex’s No. 3 Hair Repair Perfector (the “Product Distribution”) at their residential address. Settlement Class Members who do nothing will, by default, participate in the Product Distribution; or
(2) receiving a $20.00 Interac E-Transfer by submitting an E-Transfer Request within the E-Transfer Deadline (the “E-Transfer Distribution”, and collectively with the Product Distribution, the “Compensation”).
In addition to the Compensation, the Defendants have also agreed to pay the Settlement Expenses and Class Counsel Fees and Disbursements on top of and separately from the Compensation offered to Settlement Class Members. The Product Distribution and the E-Transfer Payment will be completed through a Settlement Administrator (the costs of which will be borne by the Defendants).
