None of these ruin the hair. They are all wash off products to spray/dab on your roots to give you a few extra days before going to the salon. I have also studied hair and I love a product not mentioned but similar to the mascara looking one. But it's a gel that doesn't stain and looks natural on the hair without a waxy looking coating. But again, none of these alter the state of health or the real color of your hair. It just goes on then you wash it out. Just make sure there's no alcohol in it to avoid drying out your roots.

If you deep condition with coconut oil at least twice weekly prior to washing, you shouldn't end up with any issues. Don't forget to eat well to strengthen your hair. Beauty starts from the inside!

Sorry I wasn't clear ! I wasn't trying to one up you PamilaWofford!

If you aren't terrible it at, you should learn how to color your own hair. Going to a salon is incredibly expensive, and usually you're paying a HUGE amount of money for things you can do just as well at home. It's an art, don't get me wrong, that's why they charge as much as they do, but if you can't afford it, maybe it's best you don't go at all. It's honestly not difficult to follow the instructions and color your hair at home. But it's also easy to mess up, I guess.

Well then it should labeled temporary solutions. These contain metallic salts that can destroy the texture of your hair leaving it porous and unable to properly hold color

Coconut oil has nothing to do with the color it will turn your hair. It depends on the amounts of Pheomelanin and Eumelanin.

Yeah, skip the salon enjoy your cheaper product, and sub par hair. And then us hairdressers will see you in the salon and charge you $300 to fix it. Not smart.

I wasn't discussing the colour, just the condition of the hair in general. Some dyes can make your hair pretty ragged.

@pamilawoffard they all say temporary touch up.. And no not all of them contain metallic salts. Some are literally just mica or dyed talc powder.

I've been using Loreal hair colouring for years and at 67 my hair is still healthy and thick and in great condition. That's using 10+ Blonde. I've always used good shampoo and conditioners though either John Freida or a Salon Brand.
