Need help with my blonde

It sounds like you are a "summer".

If you want dark blonde, you may want to choose one with a violet or neutral base, (although, your hair does not look very yellow in the picture, so it may go very ashy with the violet. Summers do look best in ash colors, but you don't want it to go purply or gray looking). You'd definitely want to test strand it because not only do you want to make sure your color goes right (base colors can show up on very lightened hair), but you want to make sure it works over the gray, as sometimes gray can be resistant to dye.

Lightened hair is usually very porous due to chemical damage, so you may run into two issues with that. One is that it absorbs dye very well, so it may initially come out darker than you wanted, but it will also fade very fast. You may be back to almost light blonde in 1-2 months because the dye just slides out of the porous hair, even if it is permanent.    ....Although, if it didn't take too many runs with the mega blond to get your hair that light (if it was only dyed once or twice), your hair may not be as porous as most peoples' when they go to that shade so these might not be as much of a problem (it sounds like you started off pretty light).
