Unless you’re worrying about how to pass a hair follicle drug test the literal night before a drug test at work or something, then I’ve got some great news for you. A hair test is actually pretty simple to pass compared to some of the other tests, but it sucks because you have no choice but to damage your hair to a tragic state. If you’re somebody who takes great pride in the health of your hair, then this might be a very difficult process, and it can cost quite a bit. There are some well known and vouched for detox shampoos but those will cost a couple hundred, and then you’ll have to pay for everything you need to start repairing your hair after the test. Given this information, you might want to think about whether or not keeping this job is really worth it to you. If you’re in a position in which you have time to find another job, you might prefer to simply do that. If you do really need to know how to pass this hair follicle drug test no matter what and are willing to do whatever it takes then here’s a couple more or less simple methods.
   Baking Soda + Bleach + Detox Shampoo
   The alternative to this is using straight up laundry detergent, but I’d be lying if I said this one is much better. It might crush your soul to do so, but this is what you’ve got to do. First wash your hair and then bleach it, as if you were dying your hair. If you normally color your hair, you can go ahead and do that now too, but this is optional. Apply a paste of baking soda to the scalp and hair making sure to really work it in as much as possible for as long as you can afford to. Let it sit for about half an hour, then wash everything out with a reputable detox shampoo like T/Sal or Zydot.
   Detergent + White Vinegar + Detox Shampoo
   This one is a real nuke on your hair. Apply white vinegar to hair and scalp to strip all the oils and then add whichever detox shampoo you ended up choosing. Be careful, because if you google ‘how to pass a hair follicle drug test’ you’ll see a whole lot of bogus, scam results. Make sure to look into whatever you choose to buy very diligently and make sure you only order from official, verified vendors. Next, you’d have to rinse your hair and apply a sizeable amount of laundry detergent and wash vigorously. Rinse and repeat a couple times if you’re able to torture your hair to such an extent.
