The Costco Canada recall notice warned customers not to continue using the affected Renpure Tea Tree & Rosemary Scalp Rebalancing Shampoo and Conditioner if they purchased the product during the affected sales period.
According to the official notice, the recall was initiated “out of an abundance of caution” after concerns emerged regarding possible elevated microbial contamination levels in certain bottles of the shampoo and conditioner sold at Costco stores in Ontario and Quebec.

These lot numbers can be found on the bottom of the shampoo bottle packaging. Customers who locate either of these lot codes are being instructed to stop using the products immediately.
The Costco shampoo recall has become especially important for consumers with sensitive skin or scalp conditions, as elevated microbial levels in personal care products can sometimes trigger irritation, redness, itching, or discomfort.
Why the Costco Shampoo Recall Was Issued
According to Mav Beauty Canada Inc., the Renpure Tea Tree & Rosemary Scalp Rebalancing Shampoo and Conditioner recall was issued because of concerns over possible elevated microbial contamination levels.
Although officials stated there have been no reports of serious adverse reactions connected to the recalled shampoo products, the company emphasized that the recall is being conducted to maintain high product safety and quality standards for Costco members across Canada.
The company explained that:
“Some individuals may experience mild skin irritation or sensitivity.”
Microbial contamination in cosmetic and personal care products can sometimes occur during manufacturing, packaging, or storage processes. While not every contaminated product causes harm, companies often issue precautionary recalls to prevent potential health issues and maintain consumer trust.
Costco Customers Eligible for Full Refund
Costco Canada confirmed that customers who purchased the affected Renpure Tea Tree & Rosemary Shampoo and Conditioner products can return them to any Costco warehouse for a full refund.
Consumers do not need to continue using the affected shampoo and conditioner products if their bottles match the recalled lot codes. Costco advised shoppers to immediately discontinue use and bring the product back to their nearest Costco location.
The Costco refund process is expected to be straightforward, as the retailer continues managing multiple product recalls and safety notices across Canada throughout 2026.
Canadian Product Recalls Continue Rising
The Costco Canada shampoo recall comes at a time when Canadian consumers are seeing increasing numbers of food recalls, cosmetic recalls, and household product safety alerts nationwide.
Recently, several products sold in Canada have been recalled over contamination risks, including dessert products linked to possible salmonella exposure and various consumer goods flagged for safety concerns.
The latest Renpure shampoo recall highlights growing consumer awareness regarding ingredient safety, manufacturing quality control, and microbial contamination risks in personal care products.
Health experts say shoppers should regularly monitor product recall notices issued by retailers, manufacturers, and Canadian safety authorities to ensure they are not unknowingly using affected products.
What Consumers Should Do Next
