Biosense to Alfaparf

Converting a client's Biosense formula into Alfaparf? 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.

88Biosense shades in The Shade Library
35have an exact Alfaparf match: same depth, same reflects in the same order
53Biosense shades have no exact Alfaparf equivalent

Why a same-number chart is not enough

Biosense and Alfaparf levels line up, but their reflect structures don't always. Only 35 of 88 Biosense shades have a Alfaparf shade with the same depth and the same reflects in the same order. For the other 53, the nearest Alfaparf shade changes the result, and knowing that before you mix saves a correction.

Sample conversions

The straightforward ones: standard natural shades where both brands print the same level. Any chart gets these right.
