Oily Scalp - Cheongmijeong Black Grain Shampoo

I first came across Cheongmijeong Kelp Shampoo through an acquaintance about 9 years ago. I used it consistently because it was gentle and didn't cause any breakouts. Then I discovered there was a Black Grain Shampoo for oily scalps, and I've been using this product for years now. My scalp isn't just oily; it's sensitive, so I can't use regular shampoos with lots of chemicals because they cause redness all the way down to the back of my neck. I think this might be the perfect shampoo for my scalp, haha. I recommend it to anyone like me.
