How Does It Work?

Hair grows at approximately half an inch per month, making the 1.5-inch sample ideal for a 90-day overview. A standard test requires about 100 milligrams of hair and is performed with minimal discomfort. Results are typically available within 1–3 business days, with positive findings sent through confirmation testing for accuracy via gas chromatography-mass spectrometry.
