Keep researching... THCA stops depositing into the hair 2-3 days after your last smoking session. So if you cut your hair to the scalp 7-10 days afterwords, all new hair growth is clean hair.

Longroad, you have been clean plenty of time and should have nothing to worry about. Also, most collectors look for a hair sample of 3/4 of an inch or more when testing. Cutting your hair really short will only force them to find the sample elsewhere.
