Also want to add to this question and apologize if this is bumping... but something in their FAQ confused me

How is oVertone different from my homemade cocktail of dye + white conditioner?This is our favorite question! The oVertone conditioners were created as a bigger and better answer to color fading, with a massive advantage over a mix of deposit only dye and standard white conditioner.
1. First and foremost, all hair dyes contain a heavy amount of various alcohols in them - this is how semi permanent dyes open the cuticle of your hair to deposit as much color as possible. It's a great process for dyeing, but also means that regular use of these dyes once or twice a week can seriously dry out your hair, especially if it's already been bleached and processed in other ways. The oVertone conditioners are free of these heavy alcohol contents, which means you can refresh your color AND keep your strands healthy.
2. What's more, if you're mixing those dye-based alcohols with a regular white conditioner, you're not only preventing the healthy oils and emollients from doing their jobs, but you can also screw with the pH balance of your mixture in a way that messes with your color and the health of your hair. All of the oVertone products are balanced to heal your hair while you stay bright and beautiful.
3. It's easier. No mixing.

4. If you've got a bright color on your head, the oVertone Vibrant and Extreme lines provide more color per teaspoon than a half and half mix of dye and conditioner. You can stay SERIOUSLY bold, 24/7.
5. If you're rocking a pastel shade, you don't have to worry about the splotchiness that can come from off balance pH or so-so mixing. Your pale color will be the same tone every single time, no guess work required."
Specifically looking at the first two. Aren't most dyes people use to get "fantasy" colors conditioning in themselves? After much browsing on this thread I thought it would not be damaging to create this concoction of dye and conditioner.
