That's probably the standard wait 4 weeks before using any sort of peroxide / developer kind of stuff. That 4 week wait is to allow time for damage to show up so you can assess whether or not your hair can handle more processing.
In the meantime do NOT use any form of bleach, or box dye that you have to mix before application.
The good news? You could slap a veg-based semi-permanent / direct dye on it now (eg Special Effects, Directions, Adore etc etc) if you want because they don't damage your hair at all.
In future read ALL the instructions before use
