Biosense to Redken

Converting a client's Biosense formula into Redken? 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

26have an exact Redken match: same depth, same reflects in the same order

62Biosense shades have no exact Redken equivalent

Why a same-number chart is not enough

Biosense and Redken levels line up, but their reflect structures don't always. Only 26 of 88 Biosense shades have a Redken shade with the same depth and the same reflects in the same order. For the other 62, the nearest Redken 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.
