Cannabis use is detectable with hair tests and is generally included in the standard hair test. Hair tests generally take the most recent 1.5 inches of growth and use those for testing. That provides a detection period of approximately 90 days. [5] If an individual's hair is shorter than 1.5 inches, this detection period will be shorter.
The standard length of head hair used in the test is 1.5", which corresponds to about 3 months. Body/pubic hair grows slower, and the same 1.5" would result in a longer detection time. [2] Oral fluid or saliva testing results for the most part mimic that of blood. The only exceptions are THC (tetrahydrocannabinol) and benzodiazepines.
It is also used by employers, who test their employees. [6] Hair analysis has the virtue of showing a 'history' of drug use due to hair's slow growth. Urine analysis might detect drugs taken in the past 2–3 days; hair analysis can sometimes detect use as far as 90 days, although certain cosmetic treatments (e.g. dyeing hair) can interfere ...

Growing hair is like a workout for your scalp — hair follicle cells are the most rapidly dividing cells in the body, so it takes lots of energy to produce new hair.

The use of hair analysis in alternative medicine as a method of investigation to assist alternative diagnosis is controversial [1] [2] and its use in this manner has been opposed repeatedly by the AMA because of its unproven status and its potential for healthcare fraud.
In 2015, the first government standards for testing were proposed in Colorado's legislature, when potency and microbial testing became mandatory in the state. [11] [12] [13] Colorado cannabis testing laboratories, such as AgriScience Labs, are regulated by the Colorado Department of Revenue's Marijuana Enforcement Division and the Colorado Department of Public Health and Environment.

Hair follicle with mesenchymal dermal papilla, labelled at top, location of hair follicle stem cells and thought to be site of action of DHT. Type 1 and 2 5α reductase enzymes are present at pilosebaceous units in papillae of individual hair follicles. They catalyse formation of the androgens testosterone and DHT, which in turn regulate hair ...
