Keratin - Good & Bad

It has been awhile since I applied the keratin to my hair. At this point, I'm definitely in a mixed review type situation. On the whole - my satisfaction is neutral. I really can't say that I am happy or unhappy with the product. The good just does not outweigh the bad, nor the other way around.
For the good - my hair has continued to be straighter than prior to the treatment. My hair is a little less straight than I would like, a less than prior to the second after treatment wash. However, it is not so wavy that I have to spend any prep time on it for a typical day at the office. That being said - if I were going out socially, I would more than likely use the straight iron on it.
For the bad - I definitely have to wash it daily. If I don't, my scalp feels horrible - oily and greasy and just plain dirty. I also have found that my hair is much more coarse that before. It is definitely not silky and smooth as I had expected it to be.

Luckily, I got this product for free by being a bzzagent. As such, I get free products to try in exchange for my candid opinion.
