Query: Wonderful!

I purchased this based on the good reviews I read. I will admit I was very skeptical. I have psoriasis on my scalp and I have to alternate shampoos regularly. I also have really long hair that requires a great deal of care. Upon first impressions of this shampoo I really hate the smell. I almost did not try it. I read where some people did not need to use a conditioner as the shampoo left their hair very soft. I did use conditioner on my hair (on the ends) since it is really long (almost waist length and I am 5'8"). I have since used this shampoo each time I wash my hair for the last few weeks. I have noticed a significant difference. My hair is softer than usual and remarkably my psoriasis has greatly improved (it has not cleared completely, but close). You also dod not have to use much of this shampoo either, which is a plus. I will defiantly buy this again!
