This helped instantly with my dry itchy scalp. I developed very bad dandruff, my scalp was itchy and huge flakes of dandruff. After one use there was a huge difference, it says to use once a week but I’m using it twice a week to manage my itchy scalp, but it’s definitely reduced it a lot. It’s a bit hard to use, but just need to apply it to your roots and not your ends because your hair will be dry and knotted after. It eventually suds up like a shampoo but just need to concentrate on applying to the roots and scalp. After rinsing out, I applied the ‘Smoothing oil-infused leave-in concentrate’ to help detangle my ends and using a hair dryer to dry my hair.
