Hi, I have purchased the AVEDA INVATI SCALP REVITALIZER (150ML) product and realized that it causes my scalp to be itchy and causing some rashes to my skin. This is very rare to me as my skin is hardly sensitive to any products. I have taken some pictures of the rash however I can't upload them here, could you send me an email address to attach the pictures? It's quite bad and I have to stop using it. It's really a disappointment as your product is believed to consist natural ingredients yet can cause such irritation to the skin. I'm getting a little skeptical about the quality of the product.
