Will Marijuana Smoked 90 Days Ago Show In Hair Drug Test?

If I smoked weed 90 days ago to the dot, will it show in a hair drug test? I only smoked a few times in the weeks before that and I ve never been a habitual smoker but I was exposed to second-hand marajuana smoke somewhat frequently. Furthermore, is tobacco evident in a hair test?
