Traces of THC stay in the central section of the head (from the back of your neck to the middle of your forehead) for life unfortunately. The only way to pass a drug test is to get an electric shaver (width approximately 2 inches) and shave this section bald. I have to do this once a year for my job (police officer). I know it sounds radical and be prepared for people to really make fun of you for awhile, but if it means keeping your job it's worth it in the long run.
Note: If you are a man and currently completely bald don't think you're off the hook. Hair drug testers will usually see this as having something to hide. So I'd recommend glueing some fake hair just on the sides of your head and they can take a sample from that..
By shaving her head.
No. Drugs stay in the hair for weeks.
No, nothing but not using cleans your system. The drug stays in fat and hair cells.
If you did not smoke any marijuana, and you have since washed your hair, you will have no marijuana in or on any of the strains of hair on your head, and it will not show up on any drug tests.
if you're talking about a hair strand drug test, my understanding is that marijuana can be detected in the strands of your hair for about a year.
Simple.... DON'T do drugs - period !
Marijuana or THC which is what's tested for in drug tests can be found up to 90 days when tested for in the hair. I was on probation and had to take drug tests I couldn't find anything that helped with hair tests. Since I don't know what "light use" means I couldn't tell you if it'll still show up in a drug test. I hope everything works out for you.
Yes
marijuana stays in your hair for up to a year and 4 weeks for the urine
Using a Bic razor is the only way to pass a hair drug test.
Saliva and urine drug test -YES, but the best will be to home test yourself using One or 5 or 7 panel home drug test kit (from any CVS). Hair drug test- NO
Nothing.
