I have had psoriasis on my scalp since age 18 (37 years)! I started using your product in December 2012 and after about two weeks there was no sign of psoriasis. My hairdresser got me using the product and she said it was nothing short of a miracle! I had previously had no results wtih anything else, including medication. I'm psoriasis free and my highlights stay great-looking longer! As an added bonus, my hair is thicker and is growing in the "thin" spots! Thank you so much for your product! I've purchased a supply that should last me three or more years!
