My usual (if not only) problem- bleach!

You are better to leave a bleach with lower peroxide on for longer than use a high percentage for less time. It's like trying to bake a cake at 600 degrees. You'll burn the outside and the inside will be raw still. You just wont get the best results. It lifts cleaner with a lower peroxide.

Also, I really hope I misread the part where someone advised putting a 12% bleach on for an hour. As Persianista would say... Would you like to take your highlights home in a bag?!

i agree i was told the same thing on a training course a few years ago also to ALWAYS measurer the bleach for the same reason would you make a cake and throw a egg and some flour with out measuring and for expect it to rise when i done my training many moons ago we use to use 60vol with bleach god when i think back now theses days i never use anything higher than 20vol with bleach and if it takes longer it takes longer least i know ive done the treatment to the very best of my ability and what is best for the clients scalp and hair and i know its still on her head and not in the basin

Its the same as most things, you can only go by personal experiance, Ive been hair dressing for many years but have always been back to seminars, courses for new tecniques etc and 2 years ago did my advanced colouring BUT still use 40 vol if needed without any problems with over processing or damaging hair ! but its good that everyone has different veiws !

you ever tried stripping a dark colour and need to reapply more product? ...

Yes I agree, as it dries out it loses strength, but it never stops working.

I use, and always have use 40vol if its needed, never ever had probs with damaged hair, Whats best 20 vol for double the dev time or 40 vol on for half the dev time ??? So long as the hair is in good condition and you dont overlap or over develop you shouldnt have any problems imo

I also always use 40 vol on darker hair, never had any problems with it. I also add a bit of Wella 10/1 to my bleach, I find it takes out some of the yellow as its lifting.
