So here's the deal with L'Oréal Paris Prodigy 8 Dune – it's basically a game-changer for at-home hair color. No ammonia, which is awesome because that stuff can be pretty harsh. They've got this cool micro-oil technology going on that just melts into your hair, whether you've got light or dark strands. You're gonna get solid coverage from your roots all the way down, and it totally handles grays – we're talking 100% coverage here.The best part? Your hair actually feels amazing after. Like, really soft and shiny, not all dried out like some dyes leave you. Works for pretty much any hair type, and it blends super naturally with whatever color you've already got going on. Quick tip though – if you're stuck between two shades, just go with the lighter one. Oh, and definitely do that allergy test thing 48 hours before you color. Better safe than sorry, right? Mix up the color cream with the developer, then work it through your hair starting at the roots and going all the way through. Let it sit for about 20 minutes, then rinse it out. Don't skip the conditioning mask they throw in – it really makes your hair look extra healthy and gives it that nice glow.
