I took one loratab in January (4 months ago) the hair folicle test goes back 90 days but my head hair is too short to gather 1.5 inches so they will probably use my leg hair. Im going to take the hft tomorrow. Should I be worried?

They can also use armpit hair.. pubic hair. Eyebrow hair, elelashes etc as well. THey all are slower growing and have a longer lookback than head hair for a given length,

Its all water under the bridge... if you fail.. you fail. To late to change things now.
