Will 10 volume developer kill head lice?

No, 10 volume developer is not an effective treatment for head lice. While it may have some bleaching properties, it does not possess the necessary insecticidal ingredients to kill lice or their eggs (nits). For effective lice treatment, it's recommended to use specifically formulated over-the-counter or prescription lice shampoos. Always follow the instructions and consult a healthcare professional for guidance.
