it would be very unusal for a retailer to do hair tests. too expensive. Unless your appling for a top management job I wouldn't worry about a hair test. I wouldn't worry about it anyway since there really isn't anything you can do in 2 weeks anyway. Shampoo's are b/s

based on your weight and usage, you should be fine in 2 weeks doing nothing at all. Buy test strips and find out yourself. If you are positive, dilute and use creatine and vitamin suppliments to keep your test results valid.

This will work 99% of the time, 100% if you test yourself enough to know exactly how much you need to dilute.

peace and good luck
