Colouring hair same day as washing & conditioning?

[HaveAGoodDay]

I've washed & conditioned my hair this morning. I've got a semi-permanent colour use, would the results be the same if I was to apply the colour tonight or tomorrow?

I know sometimes they say on the instructions on some hair dyes if the hair has a lot of hair styling product then you can wash the hair but not to condition - I wonder is that because its acts like a barrier to hair dyes? And I know usually it's best to leave colouring hair 24 hours after washing to protect the scalp. Just wondering if I was to colour my hair tonight, would it still take the colour ok?

Conditioner closes/smooths the cuticle which is what needs to be 'open' for the colour to penetrate, I'd wait till tomorrow or rewash and 'rough' it slightly with a towel ( no conditioner).

The colour probably won't "hold" or penetrate as well with freshly-washed hair

Yeah do it on day old hair

Also if your scalps too clean the natural oils won't protect your scalp from the chemicals (according tou hairdresser)

To MY hairdresser I mean
