A hair drug test is not a drug test that can be performed on site. A hair drug test must be sent to a lab.
A hair drug test cannot be performed on just a single hair & requires a sample of hair for testing and most reputable labs use strands that are about 1 ½ inches long. This limits the detection history to about 90 days, depending upon the rate of growth of the individual’s hair.
Essentially a hair sample is taken from the testee. The hair sample can be taken from the head but if a hair sample is not available from that source the hair can be taken from any part of the body.
Once the hair sample is obtained it is sent to a lab. The lab then dissolves the hair in a solution to look for the precense of drug metabolites in the hair strand.Some people attempt to pass a hair drug test by shaving their heads. In the absence of the required amount of hair on the scalp, body hair can be used as an acceptable substitute.
The entire hair drug test procedure should be completely documented to insure that it is accurate.
HOW TO PASS :
There is no real preparation or natural way to pass a hair drug test.
You will need to use what is commonly referred to as a ‘hair follicle shampoo’.When you are selecting a product to pass a hair drug test it is important that you pick a reputable company to pass your hair drug test. Due to the growth of hair drug testing in the work force many compaines have rushed products to pass a hair drug test into the marketplace without fully testing them. To pass a hair drug test we recommend the ClearChoice Hair Follicle Shampoo.
