Well, it takes approximately five to seven days for cannabinoids to be incorporated from bloodstream to hair. Therefore, if you only had one hit four weeks ago, the chances are low that you will test positive for THC. However, if you are concerned, there are detox shampoos and treatments available that may help to eliminate any traces in your hair. It's always best to consult with a medical professional or drug testing expert for further advice tailored specifically to you.
