The dreaded.... hair drug test

I will post the details , curious if anyone has any similar situation. And as always, would like to know how it worked for you.

My husband was offered a great job and he accepted, he is already contracted with the company so works out of the office daily. Now he will just be an actual employee of theirs. Now, on January 15 (Monday) he was sent his official email and this included the drug test. We had until Friday (1/19) to do the test. He was a pretty heavy user, daily, but generally only in the evenings. So we did endless research Monday and overnighted the aloe rid shampoo from Testclear, which by the way is extremely pricey. Monday night he started soaking his hair in vinegar and baking soda to start opening the cuticle. Tuesday night the macujo method treatments began. Wednesday morning one Mac method followed by two bleach and re-dye done by a hair stylist. Wednesday night another Mac method. Thursday morning two more Mac methods along with just shampoo methods in between. By Thursday we were so paranoid and his head was looking pretty rough. Slight chemical burns and super red head. So we decided to test on Thursday evening. We did the zydot ultra clean right before he left for the test. The test was 1/19. We still have not heard anything. And since he works out of the office we are more unsure.

He quit using on 1/14. He has thin blonde, curly hair and a pretty fast metabolism. Altogether we did 8 Mac methods, two bleach and re-dyes. And 14 aloe rid washes. No news is good news but we are on the 9th day. So has anyone waited longer than 10 days only to learn they failed?

Will post results once we are confident that he is in the clear.
