I hear a lot about oxygen additives to help punch colors back up and help control wicking in berbers. Is this something we add to the prespray, or rinsing chemistry? I also remember peroxide is good for adding oxygen, but doesn't that punch the PH level back up again if used with the rinse?
Looking for a rule of thumb for adding these things. How much? What to expect with my PH?
Thanks
