For me I concentrated on protein during those first few weeks after I colored. I did alot to my hair within a short time going from purple, to red, to honey blonde, to bleached highlights, then adding in lowlights.
For 50% of that I used rinses ( semi-permanents). Now all I really do is co-wash and deep condition. I stocked up on Roux products and I dont even use them anymore.
I started out bleaching a portion of my hair in the front and then dying it to the desired color. I used a toner on my bleached highlights.
Shoot, if i'm taking the precaution of going natural for healthier hair, the least I can do is have fun with it.
Remember to always to a heavy protein treatment before and after your bleaching. Always apply the bleach to the middle and ends first, then the roots. Your roots process quicker because of body heat. Using a toner will take away the brassy, red tones. I like using Wella Toners. If you wind up with an orangey bleached color, your going to want to neutralize that with it's complimentary color. Remember the Color Wheel.
If your hair has yellowish tones, neutralize with a violet toner. Orange with blue, etc. I like White Lady or Ivory Lady.
Also
I wouldn't go higher than a 20 volume developer even with bleach. It'll take longer to process, but your hair wont be as badly damaged. Never use a 40 vol. Stay away from overuse of heating implements and I don't recommend box dyes. If you don't want to be blond, you can always bleach first, protein treat, then dye to desired color.
