How much does bleaching affect a hair analysis test? i wanted to know in detail how tremendously bleach affects hair analysis testing and can it remove the apparent drug and it metabolites from the hair shaft.

Bleaching : Bleaching and other hair treatments such as dying or straightening do not remove drug metabolites from the hair shaft. It will not help you pass a drug test.
