Review on SATIN Satin Oxide Developer 32 Oz - Achieve Stunning Results with 20 Volume by Beeye Klaver

Update from September 23, 2021: Strange. The product is supplied without a protective seal on the bottle neck. Came in an airtight sealed plastic box with bubbles (new). Just a note. I add "Cover Gray Developer" to my hair dye/color mix and 20 volume developer for better coverage on stubborn gray hair. Although this product is meant to be used to its fullest potential, I only add one batch to my regular 20 developer to increase the coverage of grays that would otherwise be light and orange rather than mid-brown. I still get good color saturation at the roots, so there's no longer an embarrassing amount of orange. Recommended for anyone who has a problem with good gray hair coloring!
