my friend bleached my hair a while before i went to the salon to get it japanese straightened, but my hair dresser told me that it would screw up that part of my hair. it kinda did, but it's better now & he told me not to bleach it again. but i think my hair color is kind of bland right now, and i feel like dying it with either gatsby hair dye or palty hair dye, but i don't know if that will damage my hair. i japanese straightened it on like dec. 3O or near it... so will dying it affect my hair now? thanks in advance.
