Redken Shades EQ Processing Solution is the dedicated developer for Shades EQ Gloss. It is approximately a 7-volume hydrogen peroxide developer (2% hydrogen peroxide) that is formulated to hold an acidic pH and stabilise viscosity.
Used with Shades EQ Gloss, it ensures the proper tone, depth and durability, and it does not lift the hair's natural pigment. Mix it in a 1:1 ratio with Shades EQ Gloss. No other developer should be substituted for it, as the results can be unpredictable.
This is the 1 litre (1L) size.
