What is hair testing for?

There are dense capillaries around the hair follicle. During hair growth, inhaled drugs enter hair follicles from the blood and are fixed by keratin in hair. In about 3-5 days, the hair containing drugs will grow on the scalp surface and grow outward at a uniform speed, and the drugs will stay in the hair roots for a long time. Hair testing is based on this principle to identify the time and dose of drug abuse.

Hair can detect 38 common poisons (drugs) such as methamphetamine, amphetamine, ecstasy, ketamine, morphine, codeine and marijuana in scalp.

Compared with traditional detection methods, hair detection can detect drug abuse in the past six months, and the detection results can be used as an effective basis for drug control and detoxification; Hair detection can screen a variety of drugs, reducing the complicated procedures of drug screening; Hair detection has the advantages of simple operation, rapid detection, easy interference, good accuracy and stability, and no need to refrigerate samples.
