i need some some advice

so i smoked weed for the first time at the end of janruary. i took 3 hits two from a bong and one from a steam roller. i have a drug test friday and it is a hair test. i need to know what u guys think. i am inclined to believe i will fail but i though maybe since it was my first time and i didnt even feel n e effects i might have a shot at passing. needless to say i am freaking out so n e advice would be great. getting some sort of cleaner via the internet is not possible nor are n e crazy home remedies as i live at home with my parents.

Who is making you take the hair test and why?
