I took a 2mg Xanax in January and I have a hair follicle test I took today. I dyed my hair blonde like 2 months ago. But I was wondering if it will show up on a hair follicle test. The doctor cut the hair far away from my follicle so I'm worried they will get past usage, that was done outside the 90 day range. Do you think it will show up since it was over 4 months ago? And I have dyed my hair blonde twice since then.

Hair tests are designed to measure consistent use over time. If you only took the Xanax one time you should be fine.

You should be good to go!
