Hi , if you want to bring the hair up to a nice light creamy blonde without any orange tones and without burning the scalp ,
you could try a special oil bleach especially made for on the scalp applications its called proclere oil bleach
it is very gentle and you only need to use 6% with it ( full ratio instructions are in pack )
first you bring the roots up to a nice creamy blonde
just like the inside of a banana skin ,
(it has got to get just past that baby chicken yellow stage )
but not too white either,
then wash off
and tone with a toner of your choice from the proclere toner range especially made for bleached hair ,
the toner range is safe and ever so gentle on bleached hair and you wont get any grab with it either,
(full instructions are in box)
it is kind to your hair and scalp and does not itch or burn :hug:
but as Jrobinson said never take bleach or lighteners
through the ends of the hair
as it will always get dry and damaged whether it is bleach or a high lift tint
