Hair Coloring

[Catrin]

I've not done what you describe (though I dye my own hair), I would be a little concerned about adding more chemicals over recent dye. It might be fine, but I would be concerned about getting a different outcome than what you hope.

It might be fine though, in all the years I've dyed my hair I've not tried this so consider this worth as much as it cost

I only do single-dye jobs myself, but if you have a sally beauty nearby theyre usually really great with advice on how long to wait between colors/adding highlights, how stuff will interact, etc. My mom helped me do some wacky stuff to my hair in high school with their advice.
