Stupid question I know, But to this date I've never done it!.
If for example I applied 66/0 koleston perfect to 100% white roots and wanted to refresh the mid lengths and ends with colour fresh 6/0 could I literally just apply the 66/0 then in the final 20 mins apply the colour fresh?
So My question is this .... Do permanent and the matching shade in Demi permanent match up when refreshing mid lengths and ends when colouring roots with permanent or do u see any obvious colour difference...
