Brief Answer:
YES
Detailed Answer:
The detection is on the basis of when the hair was at when you smoked. My hair is chemically stimulated to grow fast... ONE inch a month, most people's hair grows slower. So, if I used pot ONE month ago, the hair at ONE inch out would be positive. In you, that would be 2 to 6 inches from the skull and if you show up with a bald head they are going to fail you. They are likely to find pot at 2 to 6 inches out from the skull. There is no way to make it NOT show. There are easy ways to make it be falsely positive (shampoo in pot).
