Probably yes. Leg hair takes about 4 months to fully grow so anything that has been in your system in the last 120 days will show up in your leg hair.
Yes
No, hair test detect drug usage : 36h after - up to 90 days.
No, not really as it can detect up to 90 days, maybe longer depending on how often you use, also hair growth.
a hair folocal test can go back up to 20 years
yes - and they can detect it for up to 90 days.
They can detect hydrocodone for up to 90 days in the hair.
When I got my hair follicle test, the guy who was doing it informed me that hair shows your usage history depending on length. every inch and a half of your hair will show 90 days into your history. So someone with longer hair can be tested up to a year in their usage history.
'a hair folical test can trace drug useage 20 years back' This is a lie. Hair tests only test back 90 days. It is possible to test back further, but this is rarely done, and the absolute longest that the test can trace is 4 years (the max lifespan of human hair) but this would require them to take about two feet of hair.....not possible. The chance of testing positive from 8 months ago....no chance! Whoever answered this question, keep your lies out of here, this is not a place for intimidation.
A hair follicle test can be used to identify specific drugs used by the person being tested. The test can usually detect drug usage over a longer period of time.
It is certainly possible to dye hair twice in two days. Most companies supporting hair dye products and hair health are against this.
90 days minimum...Up to ten years depending on how often you cut your hair.
The length of time nicotine can be detected depends on the type of testing used. Blood tests can detect nicotine up to 10 days after quitting, urine tests detect 3-4 days, saliva tests up to 4 days, and hair tests can detect nicotine up to 3 months after quitting.
Depends on how long your hair is.
