Hi everyone!
I am a non pro with some experience and a little knowledge. I was hoping I could get advice on how to dye my hair on my own (using professional products), but now that I read this thread I won't do this anymore. I totally understand that pro stylists are not going to teach people how to do their own hair after years of learning, and I know everything that could go wrong in DIY.
I actually live in Brazil and in my town there aren't many good stylists. The good ones cost more than I can afford, and I also don't like their style very much, they're quite old-fashioned. It's a full minimum wage for highlights and color - imagine something around 1000 USD or GBP. There are certainly many stylists worth this price, but I really can't afford it.
