I find it interesting that this product is to be mixed with 20 vol OR 6 vol developer. There is obviously a huge difference between those, 20 vol being way stronger and potentially harsher on hair that has presumably just been bleached, so I wouldn’t 6 vol be a better choice?
Can someone explain this to me? I must be missing something.
Thanks
