On my 7 level natural hair, I see no difference when I try on a blonde. Similar problem with some other apps. Very few really light blondes. Almost all are around 8 level and they make no difference. For me, it's useless. If you try darker/brighter colors, it's more noticeable. Choose global style, or you won't even notice it on max strength.
