Works the way I used it. I purchased this about 2 years ago and only just opened it. I used it after putting on leave-in conditioner and then followed up with kinky curly's polishing oil. This worked better than ecostyler for me and definitely has an elongating effect. I like that the ingredients are more natural and i don't get a flaking problem which is a big plus since some gels usually give me that issue.

This book is overall really great as a starter and the practice tests are SO HELPFUL. I think that if you want to do really well on the GRE you may want to consider buying additional books as this one does not go too in depth on the math concepts. I also found the practice questions easier than what I have encountered on the actual test in the past (for math).
