How can I tone down bleach blonde hair without destroying it?
In addition to using the appropriate toner at any beauty supply store, also look for a violet toned shampoo, usually formulated for bleach blonde or other blonde hues. The violet in the shampoo helps to reduce greens and oranges, and these usually have additional conditioners in them to protect your hair. If you can’t find something formulated for blonde’s, use something for gray/silver hair, as this is usually easier to find.
