Hi Jay- I know this might be a strang question, but here goes. I’m having a hair follicle test sometime this week (possibly tomorrow). I don’t smoke personally, but my adult daughter does, daily. She does not live with me, but comes to my house nearly every day. I know she uses my hair brush, hair bands, etc. Will this cause me to fail the test? I didn’t think about this possibility until late last night & soaked my brush in a variety of things (tea tree oil, listerine, rubbing alcohol, etc), but I had already been using my brush regularly. Will her use of my brush contaminate my hair? Thank you for your advice.
