What the Olaplex Lawsuit Alleges
The 2023 class action alleges Olaplex's No.3, No.4, No.5, and related products caused hair loss, excessive shedding, and scalp irritation inconsistent with marketing that implies the products repair and strengthen hair bonds. The active ingredient bis-aminopropyl diglycol dimaleate (BADDM) is alleged to cause scalp irritation and damage hair follicles with repeated use.
Plaintiffs allege Olaplex's premium pricing -- products costing $28-$108 -- is unjustified given the alleged damage caused and the lack of clinical support for the bold claims made.
Olaplex's Response
Olaplex vigorously contests the allegations, citing millions of satisfied users and scientific research backing its chemistry. The company attributes adverse reports to improper product use or pre-existing conditions. Related: DevaCurl hair loss class action.
Status 2026
The Olaplex class action is in active discovery. No settlement has been announced.
