Well...: Blood and urine are filtered rapidly. The hair has a longer life and there are no filters, so the THC stays until the hair falls

Hair testing: Hair follicles trap and filter traces of the drug in their growth period. And as the gradual growth of hair is inevitable, these chemicals are found to be stored in the hair and can be found during the hair drug test.When compared with urine specimen testing, hair testing provides nearly twice the number of positives and a longer detection window.

Hair stays: thc stays in the hair longer than in the blood and urine. This is because the blood is constantly being filtered (cleaned) by your kidneys and the urine is regularly eliminated from your body and replaced. Your hair, however, does not get filtered or replaced, so the thc remains.
