Images of cross-sections of hair soaked in labelled protein. The image on the left show the green hair auto-fluorescence. The image on the right shows the penetration of the labelled protein (red).
Active Delivery Studies
Fluorescence Microscopy
If you want to show that your actives deposit onto the hair surface or penetrate deeper into the fiber you may consider doing some active delivery studies.
TRI Princeton have experience in labelling hair actives and visualizing penetration using a fluorescence microscope. Fluorescence microscopy is ideal for actives that are difficult to visualize directly with spectroscopy imaging, such as peptides and proteins. TRI also has access to a confocal fluorescence microscope for higher quality imaging.
