Re-dyeing Hair the Next Day?

I dyed my hair blonde earlier today using the Glamorise hair dye, it was fairly cheap so I thought it was a bargain. Once I washed it after it was done I decided I didn't quite like the colour and it didn't suit me that well. I was wondering if it would be safe for me to re-dye it tomorrow (the day after already dyeing it) to a dark brown colour?
