Red/violet to warm brown

[Lynnz86]

My client has base 6 with 50% grey regrowth however on mids and ends it was pre lightened then red/violet applied..she wants to go to an all over warm brown. I was thinking of using bleach and warm water to strip the red/violet, apply KP 6/0 with 6/73 to roots with 20 vol, then apply 6/73 Color Touch with 10 Vol to mids & ends...I have recently qualified and looking for re-assurance! Thank you, L
