How much do hair folical test cost?

Depends... Home self- collect hair type of drug tests cost around $50- 80. Lab hair test - $100- 500 (some testing places only collect the hair sample and send it to another lab for testing). additionally a home test like hair confirm may show higher cut off levels as some labs have lower levels on certain screens so if you pass at 500-300pg its still iffy if you can pass at 200pg from a certain lab
