I gave away my colored hair for testing to my brother. But now I am worried about the results. Do you have any idea about the hair tests. Does the colored hair affects the results of the hair test? What should I do now? I need to know one more thing from you guys which is, for the hair results does the hair of the head and the hair of the body does the same thing? Does it make any difference in any ways because after all both the hair is from the same body?
