Polar Haircare Hair Dye Shampoo (Jet Black)

Polar Haircare Hair Dye Shampoo (Jet Black)
Our read

Why our pick wins

The same oxidative format as ours, but built on PPD with Cocamide DEA and extra dye intermediates on top. We removed PPD and it did not — which, with the shorter mid/high list on our side, is most of the gap between the two scores. It also costs about double.
