Hair testing can detect alcohol use regardless of whether you cut, dye, or style your hair.
Strands of hair submitted for testing can come from the top of the head or another area of the body, such as the armpit.
Detecting Alcohol In Hair
Alcohol can remain detectable in the hair for 90 to 120 days, on average. Due to this long detection window, hair testing can be useful for detecting repeated alcohol use.
What Factors Can Affect How Long Alcohol Stays In Hair?
Not everyone absorbs or metabolizes alcohol at the same rate. The amount of time alcohol stays in the hair can vary based on a variety of factors.
These factors can include:
- age
- how much alcohol is consumed
- history of alcohol abuse and dependence
- overall health status
- liver and kidney function
Older people, people with a higher body fat percentage, and people who have impaired liver function may absorb and metabolize alcohol more slowly. This can result in a longer detection window.
