Taking into consideration the fact that there are tons of different detox products, one can hardly assume that the instructions for all of them are the same. With that in mind, it is easy to understand that the requirements for the product to be taken in the first place are different as well. Certain products involve certain time of abstinence, following of specific diet, exercise, and so on.

-          Hi, I think I need to return the product.

-          What is the reason for return?

-          Well, I do not think I will be able to use it. I saw on the web-site that for the product to work I have to be clean for a certain time, and I am not. I just used some, and my test is tomorrow, so there is no way this will work now. I wish I knew it earlier; I could have stopped last week when I found out about my hair drug testing.

-          Actually, there is no 48 hour requirement for a hair drug test, since detox shampoo only applies to the outside of the hair structure regardless of the toxin level. You need to stay clean of toxins before consuming a product internally – the lesser the toxin level in the body, the easier it is for the product to work. It is different with the hair products because toxins in the hair accumulate over the period of time, and by staying clean that level does not go down.

-          Oh really? So I can still use it now? Great! For some reason I did not think of that! Cool! Thanks!
