Blonde->Black Hair Coloring: Bleach first?
I am planning on dying my hair from dark blond (level 7) to black (level 1). My friend is telling me that I should pull all color out of my hair before dying it black so that I do not get unwanted colors in it. However, I have very fine hair and I am worried about the amount of damage that pulling the color out of it, then dying it, will have upon my hair.
My sister dyed her hair black without bleaching it first. It is now a combination of blue, green, gray, brown, and blond. She had her hair dyed brown and highlighted blond previous to dying it black. I will do anything to avoid this, as it has only been a few weeks since she dyed her hair. I do not have the money to dye my hair every few weeks, not to mention that it would destroy my hair, if I were to do so.
Also, I am not willing to have my hair professionally dyed, as I can not afford that at this time. If anyone could recommend a good dye, it would be much appreciated. I already am planning on using Loreal's Quick Blue bleaching powder, if I do decide to bleach it. If anyone has used this, I'd love to know about your experience with it.
Another worry of mine is that my scalp was recently sunburned to the point of where it was peeling. I am pretty sure it has healed in the few days since then, but would it be a bad idea to bleach/dye my hair directly after it healing?
Any help offered would be wonderful. Thank you in advance for any replies.
