The CTPA statement explains that “consumers who have bought cosmetic and personal care products that contain BMHCA, can be reassured that these products are still safe to use. They will have undergone a rigorous safety assessment by an expert safety assessor to ensure their safe use.”

“I think that awareness is key for consumers and they should have the knowledge of what is actually in the products that they use,” Dr Raj Arora, GP and aesthetic doctor, tells Stylist. “I don’t think it’s a cause for concern if you are using an older formulation of the Olaplex product.

“Doctors are still learning about the actual impact of endocrine disruptors on the body and the ingredient should not be amplified as a direct cause of infertility. We need more scientific research to back the exact impact of such chemicals.”
