Yes every drug stayes in your hair for a long time. Klonopin is a long lasting benzo (nerve pill) actually called a nitro benzo because is it a long acting nerve pill that builds up in your system and released slowly. That if taken daily will stay in your urine for up to 4 - 6 weeks alone it will be in your hair taken in almost any amount. Hair tests are so expensive they are usually not done, but when they are they can usually tell the drugs you took and around when they were taken in time..
Also I am not sure but I herd of people dieing there hair with bleach to mess up the tests or if yor a giy buz your head and bleach the rest lol, dieing your hair might help as it would kill the hair maybe releasing and taking out most of the stuff but thats just what I heard
