1 doctor agrees

In brief: Doubt it

Zdot is an expensive shampoo ($34.
95 for one use, and that's "guaranteed" for only 24 hours because your body oils will re-contaminate the hair, supposedly.) once you've used meth, the drug could be in your hair for 3 months. If using at all, it's very dangerous and very addictive. Please get help for your drug use. http://www.crystalmeth.org/cma-meeting-directory.html.
