Because hair follicles can trap detectable metabolites within its walls, without any "official" way to clear them. Hair tests are considered to be the most accurate forms of drug testing.
People have passed!, seems there are ways to cheat the hair follicle drug test, but its not a simple task. Lets look into what works, what people have tried and why its so difficult to do.
I'll Cut to the Chase, What Works
There are a bunch of products out there and it seems like new ones come out Evey year. One thing remains the same, the Mac method.
It has been around for ever and I personally know a few people that have passed using it. The only problem is the time it takes to do it, how badly it damages your hair and the price of Nexus Aloe Rid.
The Mac Method is probably the oldest method used to pass hair drug tests. This takes a number of steps to pull off. The goal is to actually break open the hair follicle in order to clean the inside as well as out.

Why is Aloe Rid So much?
Unfortunately, this method was created along time ago and required the use of the old Aloe Rid. Original Aloe rid was very rough on hair and after a ton of complaints and liability issues, NexXus decided to pull Aloe Rid off the shelf.
A few individuals with great foresight knew how valuable Aloe Rid was and hoarded it from liquidators. A couple of years later, Nexxus reintroduced a gentler version of Aloe Rid to the market. The new version is currently available at any drug store, but is not the same as the original.
You cannot detox your hair with the new Aloe Rid!, The original is in limited supply and the price meets the demand.
I had been trying to put it of because I know how damaging it is. I heard the story from friends of friends, this detox shampoo will destroy your hair. At the time I took pride in my thick blond locks, but being broke and miles away from home, I had no choice.
How to do the Mac Method (Macujo Method)
For about 4 days I followed the same set of steps. If it was overkill, or could have been simplified, I'm not sure.
A quick rinse with Tide Detergent
Soaked hair with vinegar, 30min with shower cap on
Rinsed and lathered in ALoe Rid, left on for another 30 min
I repeated this for days before the and passed!
