Hair is formed under the skin and pushes its way past your skin. Now once it has past your skin it dies tripping the DNA that flowed in the production of that follicle. So depending on how long your hair is how much further back a DNA test can go; 10 years seem to be the average.
*When testing via hair follicles, there is a standardized period of 90 days, although it could be used for a longer period. When testing, the length of the hair sample taken tends to be limited to an exact average of growth over a 90 day period, which is why the test can reveal results for this time frame.

How can you pass a hair drug?
You need 90days to clean out naturally. The hair test goes back up to 90 days and it takes about a half inch of hair for every 30 days of usage so in no toxins are placed in the body for 90 days then you will clean out naturally. Shaving your head and body are red flags to the person preforming the test will pull from leg hair , arm hair, or sometimes the pubic hair. Usually they only go back 3 month . The longer they go back the more expensive the test. I have had to take a hair test in the past for probation reasons because they thought I was diluting my urine samples but were not sure.
