Henna Hair Dye Can I Use Henna Hair Dye On My Already Dyed Hair?

Can I use Henna hair dye on my already dyed hair? - henna hair dye

I used my hair blonde black light - color, as I long, dark roots are about 4 cm. Ive just put a mahogany stain semi Perminant copper on top and I like very much. I use henna dye, a similar color as a semi-permanent disappears reach.

Is this possible?
Thank you:) x
