113 days is also beyond the 90 day point where the metabolites start to break down. The belief that once the THC is in your hair, it stays there without breaking down for the rest of your life as long as that hair is uncut is false. This is why labs can only test 90 days (the average is .5 inches per month so 1.5inches = 3 months = 90 days) because after 90 days, the metabolites break down and cause the test to be inconclusive.
If your story is true, then you will be fine. My advice going forward is: drop the MJ. I almost cost myself a great internship which will turn into a great job because of smoking during college. Fortunately, it was a small dosage over a short period of time. Most high-quality jobs/businesses are increasing their usage of hair tests for pre-employment screenings. You have too much to lose.
