    The time element and hair color are unimportant. The amount and means of ingestion are what matters.

    First small amounts, single and infrequent use, of THC do not show up in hair drug testing and orally ingested THC do not show up on hair testing. That makes you safe from both standpoints.

    Ref:
    Auwärter, (2010) Hair analysis for Delta9-tetrahydrocannabinolic acid A--new insights into the mechanism of drug incorporation of cannabinoids into hair. Forensic Sci Int. 2010 Mar 20;196(1-3):10-3. Orally consumed THCA does not show up in hair. This had been preiously noted by Huestis 2007.
