How long does meth stay in your hair?? :(

Forever so u better not ****ing do it!

Don't do meth and you'll be fine. Think of your hair as shingles on a roof, as you build up layers of shingles they remain the same composition as they were when they were installed. Or you can think of it as rings in a tree, once the evidence is there it's there. So don't do drugs. And thanks for the unfair disagree but I was being serious

Not that O_troubles' post didn't have any merit... but to answer your question, the drug trace in your hair is actually kind of like tie dye... it'll stay there as long as you have that hair.
