Detailed Answer:
Hello

Welcome to Health Care Magic.
My name is Dr Muhammad Ahmad & i will look into your problem.

I have gone through your query and would try to help you in the best possible way.

I understand your concern, actually hair testing is very unpredictable if you ask me the chances.
CHANCES OF POSITIVE TEST:
(1) If you took 2 hits on same day there are almost no chance of it appearing in the test after 3 weeks of consumption.

(2)f you took it at on two different days then in this week there is 25% chance of a positive.

AND

In next week there is 10-15% chance of a positive.

Here i would like to mention that tested metabolites CAN NOT be wasted from hair with shampoo, neither is there any medicine which can help it make negative, as more days pass chances of a positive test fade away reaching to zero after 100 days.

Here i would suggest you not to panic, chances are low for 1st time consumers even those who consumed 5 times a day showed just 52% positive test.

Hope I have answered your query. If you have any further questions I will be happy to help if not then don't forget to close the discussion and rate it.
Wishing you good health !!
