Want to color dirty blonde hair to deep red. what if I want to go back to blonde?

If you're already anticipating not liking it...I wouldn't do it. Sounds like a lot of unnecessary damage, red fades super fast, so you'll have pink/orange hair before long. You have to redye red hair very often to keep it looking nice. Red hair bleeds and transfers,you have to be careful with shampooing, no hot water..only cold. You'd have to strip the hair color out with a color stripper, than it'd probably be orangey/brassy, than you'd have to bleach it and tone it/re dye it. You being a natural blonde, you probably don't have the strongest hair, It might just make your hair break off.

Blonde isn't really a hair dye color unless you have super light hair, if you want to make your hair lighter than you'll have to bleach it. You can't mask dark colors with light colors, only vice versa.

If you didn't like the red, the only option to get it back to dirty blonde would be bleach. You can't dye blonde on top of red! I wish you could, though. You'd probably have to bleach to a 9 or a 10 blonde shade, and then you could dye it a dirtier blonde colour and get highlights done or something.

I find blonde tresses with pale skin to be attractive, and dark hair with tanned pores and skin to also be attractive

Black hair blonde is okay but it's simply most blonde haired girls are actually idk a wannabe their just annoying but I'm just saying SOME dirty blonde hair not all cuz there are truly nice ones too.

strip ur hair color
