Instruct: Classify Amazon reviews into positive or negative sentiment
Query: just okay

I liked this book but I didn't like how she advertised her own products through withholding information. For example, she recommends a conditioner that stimulates but never talk about what other products can be used to "stimulate." Instead, she sells her conditioner as seemingly the only product on the market that does all of the things that a conditioner should do. That makes me distrustful especially because her other products contain ingredients that aren't so great for your hair. Good try . . . but I think the book Grow It was a lot more useful.Also, she straightens her hair way too much for someone who really wants to grow Black hair to its maximum length and health--whether through chemicals or heat.
