What happens if you bleach over bleached hair? How long do wait?

What happens if you bleach over already bleached hair??

How long do you have to wait until you can do it AGAIN?

Do you need to wait until your hair returns to a certain chemichal balance? “ph” balance or something?

DETAILS: Ok, so I had my hair black for 6 mo. and then I stripped it twice… then I bleached it. Then I bleached it again. Then I toned it twice to get the orange out (YES this was all with professional products because my mom’s a hairstylist). I WANT my hair to be platinum/white/ash. However, after all that process, my hair is NOW a golden blonde. I have noticed that some of the strands are really strange like. like… no hold, taffy? Pull apart strands when wet… like broken ends… =/ I know thats very bad but im determined to get my hair how I want it. Will they get stronger if I wait because of the “ph”(or whatever it was) balance?

Please no comments on asking my mom because she doesnt remember some of these things, hasnt been in the hair business for years.

THANK YOU SOOO MUCH!!! XD
