It is not always necessary to bleach your hair before using these semi-permanent hair dyes
as some colours may show up on unbleached hair or give a sheen/glow to the hair, however for a really good vibrant colour it is recommend these dyes be used on lightened or naturally pale hair. Yellow or Orange tones in hair can often be neutralised using toner (see under How To...Use Toners section).
Don't use the same tint bowl, tint brush, gloves etc for dyeing hair that you used for bleaching your hair - plastic containers can often retain residue of their previous contents and therefore you would be trying to apply dye to your hair that has faint traces of bleach in it - this can cause the dye not to stick and streaky/patchy areas.
Skin Patch/Sensitivity Testing is highly recommended before using these products and, as with all hair dyes, if a reaction occurs rinse off immediately and discontinue use.
Stand Testing is also advised as this will give indication of colour result and brand suitability.
More information on Strand / Sensitivity Tests can be found on under the How To section.

Semi-permanent hair dyes are not permanent and therefore should not damage your hair however always try a strand and sensitivity test before use.
