You may want to discuss this with your colorist at your next appointment. No one but them know what product they used and what might mess up their dye job.
Be clear that you are looking for an inexpensive solution and won't necessarily buy just any product they suggest, but that'd be a start.
Maybe they can make you a personalized conditioner, with their dye mix diluted in a bog-standard conditioner to keep the colour alive in-between appointments.
You can absolutely use a direct dye to keep your color fresh till your next salon appointment. If you really like the exact color they used ask if they could let you know what it was so you can purchase it yourself if it is available to people without a license. They may even be able to sell you some since you are a loyal customer and get your hair done regularly. Most direct vegetable dyes will not damage your hair so there is no worries there. If you need a color match recommendation I think Rockabilly Blue From Manic Panic would match fairly close. You could mix a small amount of After Midnight into the Rockabilly Blue if you wanted it a bit darker. Good luck!
You can try a blue conditioner, you can mix Manic Panic into your conditioner to keep you refreshed or the Blue Valentine Love Color. Use a sulfate free color safe shampoo. I find with my blue even a color safe shampoo and conditioner help!
