much of my hair fell out in early 2009 due to me plunging into the Atkin's Diet before a trip to Hawaii in late 2008. the JFC Root Awakening line had just come to my attention, and i picked up a few of the products. i do not know if this helped my hair grow more quickly, because at the same time, i started using hair vitamins, as well, stopped blowdrying my hair, etc. etc. etc. (probably, it all helped at least a little). however, this didn't dry my hair out further, didn't make more hair fall out, and made my hair much fuller after application. i would purchase it again because it did make my hair *look* healthier, and certainly didn't make it worse. it has some great stuff for the scalp in it, too, like peppermint, one of its main ingredients. i used this at a time in my life where everything was making my hair worse; this was a breath of fresh air.
