after trying it once i did not realize there might be a down side to this product [SEP] this product went on sale at ulta and my sister purchased it for about needless to say it sold out fast i tried it on a visit to her in nc and loved the results not only did it make my hair straight i kept my hair manageable and straight after sleeping on it over nightso i found it on amazon and ordered it from england as it did not seem to be available in the states any more after using it several timesit seems a bit harsh on my hair and strips it down so that my hair is unusually squeaky when clean and still wet i have resorted to alternating it with a different conditioner so i can be more gentle on my hair
