Figure 4. Fluorescence micrographs of hair treated with a control (4a) or Cutissential Behenyl 18-MEA (4b)

Fluorescence micrographs of hair fibers measure the amount of cationic material, such as 18-MEA,present on the hair surface. Fluorescence micrographs of bleached hair fibers treated with a control or 1.5% active solution of Cutissential Behenyl 18-MEA are shown in Figure 4a and 4b, respectively.
