Tren and hair folicule testing

[Needsomehelpheere]

If someone was to be tested for steroids with a hair folicule test are only certain steroids detected and if so which ones?
Does hair length have anything to do with the testing?
And finally how long after ceasing tren ace can it be detected via hair folicule is it the regular tren detection time or the regular detection time + the age of the hair strands?

i'm not sure about steroids in particular, but i know a lot of drugs can be traced back to over 6 months after the last use with the hair follicle test.
