TikToker Moncia (@monicaalebronn) was left shocked when Olaplex-branded hair oil appeared to bleach her grey towel.

“OK, can someone explain this to me?” she asks in the video, showcasing the grey, pink-stained towel. “I used this on my hair, and then I wiped my hands off using this rag."

I know I should have washed my hands, […] and it literally bleached my rag. Am I supposed to be putting this on my hair?” Monica tagged the brand in her caption, asking it to “please explain.”

Even Olaplex itself seemed perplexed by this product’s supposed reaction to the towel, as it left a comment on Monica’s TikTok saying it had never seen this before. Olaplex also urged the creator to get in touch with its team.

With 1.5 million views, commenters confirmed that the “target audience [was] reached” with Monia’s video, as a number of them claimed they had similar experiences with the Olaplex No.7 Bonding Oil. “I couldn’t figure out why my grey rags were bleaching out!” one commenter exclaimed.
