To pass a hair sample marijuana test, you can try using a detox shampoo specifically designed to remove drug metabolites from the hair. Additionally, avoid consuming marijuana and any other drugs for an extended period before the test to allow for clean hair growth. Regularly washing your hair with a detox shampoo leading up to the test may also help increase your chances of passing.
Hair follicle tests can detect drug use up to 90 days prior, depending on the length of the hair sample.
