The Tricotest is a scalp and hair analysis performed by a licensed nurse using microscopy and computer analysis to identify and evaluate scalp and hair problems. The test measures sebum, hydration, and pH levels to determine the correct essential oil treatment products to address a person's specific hair and scalp condition. Cesare Ragazzi has formulated 107 products across five treatment categories to meet objectives identified in the Tricotest, which must be performed before any products can be sold or treatments given.
