While drug testing in general is an invasion of your privacy as THC urine, saliva, and hair testing really doesn't prove whether you are using marijuana while working, you are asking them to hire you. No one is forcing you to apply for that job that drug tests.

Now if you don't know about hair testing, then why guess at it. People's jobs, freedom, and children are often at stake so guesses are not helpful. Yes, there are shampoos available that help remove THC metabolites, not mask them. There are other things one can do to reduce THC metabolite concentration in hair from chemicals to hair styling treatments and the OP can do a search on this and ask more specific questions later.
