Unprofessional who just slaps the product into the hair and massages it around! Still, the result is full coverage! I'm positively surprised at how good it turned out. It's easy to mix the 2 products and I'm glad that a detailed tutorial is included. Additionally, there is an extra treatment for about 3 weeks, which is wild for the price. I would definitely recommend this product, and as a bonus, it was easy to wash off the skin because, yes, I didn't manage the application that well. For my hair, 2 packs were needed, so remember if you have longer hair like me, buy 2.
