Hair Dye Answers

I didn’t think it would, but one hairdresser would not straighten my hair because I use Henna, which she said is a metallic dye. I am not sure of this. Can anyone shed any light on this one?

I saw an ammonia free hair color in an organic food store the other day. Would it be better for the hair to use such a product, as opposed to a chemical one…why?
Would the color still take well?

if anyone knows anything about this, I’m all ears.
thanks.
preferably something natural, organic, if you will.

I need a hairdresser who only uses natural organic products & who is experienced in dying hair with organic henna. Any advise is greatly appreciated. Thank you!

I’ve been using feria for a while (I now know that it’s pretty bad, so I’ve stopped). But I was looking for new hair dyes that would be good to dye my hair a really dark brown. I’d prefer it if they didn’t have a lot of harmful chemicals in it. Are there any good, more organic, permanent hair dyes that have a nice dark brown colour & don’t damage hair?

any idea which i can get that isnt a poweder formula & which one is any good?
