Hair colour conversion
Converting a client's L'Oréal formula into Biosense? The Shade Library matches shades by verified depth and ordered reflects, not by the number printed on the tube. Here's how the two ranges line up.
L'Oréal and Biosense levels line up, but their reflect structures don't always. Only 33 of 165 L'Oréal shades have a Biosense shade with the same depth and the same reflects in the same order. For the other 132, the nearest Biosense shade changes the result, and knowing that before you mix saves a correction.
The straightforward ones: standard natural shades where both brands print the same level. Any chart gets these right.
