Depends on the limits.

It would be very unusual if you didn't. With the exception of cocaine, hair testing usually doesn't detect infrequent use of most drugs. That is particularly true for THC/THC-COOH as these marijuana metabolites have a very low incorporation rate into hair - urine is a far superior matrix for detecting use.

If you had only 2 hits even within days of the test the chance of detection is virtually nil.

Hair test came back negative

Did you do anything to make sure you tested negative? Like shampoo your hair with a detox shampoo or using a method off the internet/
