yes indeed. The components are absorbed into the body, then into the hair, whence they can be detected.

Yes you can. You can also tell how long ago you did it (the only cath ther not with in 24 hours though thats what a urine sample is for), but there again it depends on the length of hair. The shorter your hair the less that they have to work with.

Yes, because of the residue left on the hair. It's the same with clothing or skin. You can wash your hair, but it may not get it all out. It would still be detectable, but a lot harder and if they ran the sample it would have to pass the limit of detection spec. However, you can shave your head, burn your clothes, and scrape the hell out of your skin and you might be ok.

Yes. It is not the smell it is in the hair itself. The chemical is absorbed into your body then when your hair grows it come out with the cells that make up your hair. There is no way around it. And you cannot wash it out.

You certainly can tell, due to my past I have had several hair tests. there is nothing it does not pick up even in the tinyest amount. In the end it was best to leave the mind altering stuff alone.

Yes. And washing it doesn't help - they test the root of the hair, and no shampoo gets down that deep.

yes you can, the only way to get it out of the roots is to get the stroung medicated shampoo, like T-Gel or stronger. you need a strong root cleanser or scalp cleaner.

Yes. You can also tell how long they have smoked marijuana and how long ago.
