Mixing permanent hair color with a large proportion of low volume developer
and, perhaps, adding a bonder.. does NOT create a formula which performs
precisely like an acidic "no lift" color formula formula. The option is yours, BUT if you are
currently successful and if you and your client love the results you obtain using an
acidic demi shade for this purpose....... Look before you leap into somthing that is truly not identical. B
refreshing faded hair lengths, for toning, or for performing a tint back.
