Hi all,
I am new to this forum and to hair colouring.
Would like to ask if I should use a vol 30 developer.
Basically I currently have a reverse bayalage and have my natural roots showing which are a light brown.
I would like to go to a dark blonde all over colour and my natural hair tends to go very orangey. Should I mix 30 vol instead of 20 vol with the colour?
Thank you 🙂
