Does Zydot work for Hair Test?

It is very unlikely that it will work,

HOWEVER: if you are having a drug test and you know you will fail it...and you will be in major trouble if you do fail it then it may be worth it to just try it...assuming its not too expensive...Basically if your parents are testing you to ground you or something silly like that then no, dont get it. But if you will loose a job that you really need, or if a court is making you take the test then I would just try it (assuming its not too expensive)

Basically you need to weigh the pros and cons of each. The pros of trying it is that it actually may work, however very unlikely. The cons are that it may be expensive. The pros of not trying it is that you save a lot of money because you wont have to buy the product. The cons of not trying it is that you may get in trouble.
