Can they use hair test for pre-employment?

if u have hair inch/shorter then they cant check u I believe

They can take it from another part of your body if the length is too short.

If your application says urine test and breathalyzer then thats probably going to be what you get. Don't be surprised if they do a hair test on you, I would go prepared for everything. The hair test is beatable but your going to have to bleach and redye two times and use zydot. Do an advanced search on hair testing under the name Jerry G, hes the expert on this subject.
