Can I use chemical dye after henna?

How soon can I dye my hair after henna?
Hair Dyes after Henna: If henna isn’t for you and you want to get back to commercial hair dyes, it’s fine to backtrack within the first two to three weeks. Ideally, however, we recommend that you wait two months or longer after your last henna application. If that is too long for you then aim for at least one month.

What happens if you put henna on black hair?
Henna is perfect if you are trying to achieve a shade of red, brown or black; it will not lighten the hair. Henna is tone-on-tone hair color, and it will stain the original color of the hair. Some color theory applies: Light hair is “yellow,” and adding the reddish dye of henna to it will result in an orange tone.
Does henna turn gray hair orange?
Generally henna will be much more brassy/orange when you put it on its own directly on to white or very light grey or light blonde hair. Mix a little indigo with the henna – not enough indigo to make it go brown, but just a little to tone down the red/copper.
Does henna make hair red?

Why do hairdressers hate henna?
