I was having a horrible time with the nape area of my scalp. Itchy, dry patches, redness, soreness, etc. I had been dealing with this problem since February 2014. Washing often didn't help, dandruff shampoos, hot oil treatments, oiling scalp - nothing was helping. I read the review for this product and finally tried it last Saturday - I applied it only in the problem area. I applied as directed, let it sit for about 8 minutes, rinsed, and repeated. Continued with my normal wash routine, now it's 5 days later, no itch, no dry patches, no flakes. I was shocked and pleased. Because it says use twice a week, my hair and scalp was feeling too good to mess with. I will use it weekly for a while. Then reduce usage to maybe 2x a month to keep things under control. Finally a product that does what it says. I am truly happy and pleased with the results.
