Hair follicle test coming up

I’m hoping to get some insight and maybe so reassurance if someone that has been in my situation so I was a daily smoker for about 7 months and quit about may 26th I got an offer for a really big job and heard that they drug test but it’s a hair follicle test and it says they go back 90 days well my test is around mid to late September I haven’t been exposed or anything since I quit I got a haircut in July about 2 inches on top idk if that helps and no I’m not shaving my head they will go for body hair which I heard can go back a year do you think I’ll pass been super stressed out about it thank you 🙏
