This is not a hairy question for me. Drugs show up in the hair for no more than 3 months. Even if you shave your head, you'd need to shave ALL your hair from top to bottom. When it grows out the hair would still be positive for a period of 3 months after total.

If for instance you have a short hair cut, they will cut your hair in different places on the scalp until they get about a pencil thickness of hair. The multipe divots they leave may lead you to shave off all your hair afterward!

Sounds like your employer is a bit brutal in not using chair of custody urine screens first.

Sometimes both hair and urine are checked. If they want to be real sure some one is clean, they will check urie twice a week you twice a week.

If urines are to be used for legal or job issues, they need to have chain of custody.
