Hey! Thanks for your reply

I was wondering what the deal is with the pre mixed stuff. Light Mountain, for example. I see they do various shades premixed and their dark brown one gets good reviews.

I definitely don't want black hair. And I don't have too much issue with henna showing through. It's just my grey roots/orange head thing that I really want to avoid from now on.

The smell doesn't bother me too much either! I just really want to avoid grey roots, and chemical dyes. If I had to go back to chemical then so be it. But I think that'd be just as much upkeep as the problem with semi and demi dyes is they just fade and so my greys would be visible after a short while anyway!
