Well...Im a regular smoker. Daily. My hair is usually shaved. I have been growing it for about a month now(1/4 inch). It just I have a feeling they wont be taking from my head since it's so short. But because my hair is so blond already, the bleach redye would look extremely weird, especially since I have already had 3 interveiws at the place. Im reaching the final stages of hiring, so im just preying at this point. Like I said.. It might be 4 weeks (clean) or more by the time I test. So im hoping the shampoo method will work. I was confident, but now you guys are making me paranoid. Either way I'll keep everyone posted on what happens. Pass or fail.
