i only want to bleach top half of my head, because i want to keep the black underneath, and id say ive only dyed them parts one permanent, and semi -permants about 5 times.. my hairs in normal good condition, i just want to know how many bleaches it will take please, and if my hair will fall out, just incase it isn't worth risking :).

If you do, go to a salon. I bleached my hair from black to blonde and it was in good condition, but it was breaking off like crazy. Don't do it or go to a salon!

Good luck
