I currently have all black hair, Bleaching is not a problem at all.
My eyes are a dark brown color in most lights but in natural light their and redish brown.
Im really committed to going blonde I'm just unsure if it would lookd bad.
Looking natural has never really been a big concern of mine, being that I usually dye my hair Primary/Secondary colors.
((Ex: Blue, Red, Pink, Green, && Purple.))
Im not afraid to bleach my hair I'm just unsure of the Shade/Tone I should use.
As well as what high/low lights I should use.

Here's an example of my eye color.

Try on some wigs of different shades of blond before you commit. I beg to differ about bleaching black hair though.

The bleach I use is vo. 40 it's takes black out in 15 min to a harsh white color.

From your other posts, I get the impression you are quite young. Does that stuff fry your hair as well, or is it pretty well damaged to start with ? I know a few older women, well into their 70s who did a lot of colouring procedures, some of them don't have much hair now and wonder why.

Im 16, I guess you can consider that young but no my hair is in great condition.
I have a lot of help supplied to my hair.
Such as Heat glide which repairs heat damage and moisturizes my hair, I do a conditioning treatment after every dye job.
Not too mention I alternate from just shampoo to the shamp./condit. Every other time I wash my hair.
