[Analysis Case] Evaluation of Metal Distribution within Hair

Evaluation of component distribution in hair cross-sections using TOF-SIMS analysis.

Measuring hair and obtaining the distribution of components within it is effective when investigating the effects of hair care and dyeing. We will introduce a case where gray and black hair were collected from the same individual and the internal component distribution was evaluated. A cross-section of the hair was created, and TOF-SIMS measurements were conducted. TOF-SIMS can provide distribution information on inorganic substances such as metals and organic molecules. This time, we focused on measuring the distribution of metals in the hair cross-section.
