Does Hair Dye Enter The Bloodstream? Unraveling The Mystery

Is hair dye harmful to your health? Hair dye products don’t penetrate the skin; instead, they contain color compounds that adhere to the hair’s surface. However, it’s important to note that some of the chemicals found in hair dye have been associated with carcinogenic properties, meaning they may increase the risk of cancer (1, 2). One example is aromatic amines, which were used in the past as intermediates in early permanent hair dye formulations (1). It’s crucial to stay informed about the potential health risks associated with hair dye and consider safer alternatives when possible. This information was last updated on December 1, 2022.

“Is it safe if hair dye comes into contact with your skin? When hair dye comes into contact with the skin, it can sometimes penetrate the outer layer, resulting in a semi-permanent discoloration. While having dye on your skin is typically more of an annoyance and can be unsightly, it’s important to note that in rare cases, it may lead to significant skin irritation or trigger allergies, as explained by Dr. Zeichner on August 14, 2020. Therefore, it’s advisable to take precautions and be mindful when using hair dye to avoid potential adverse reactions.”
