This was my first time purchasing Korean hair products and it was a game changer. I figured for only $6 even if I hated it, no big deal. Of course this wasn't the case the shampoo does exactly what it says it will do, cools, calms, and comforts dry irritated scalps. I love the invigorating scent and feel of the product throughout my shower. It is invigorating without being to much. A little goes a long way while the bottle does visually look a little small it contains 200ml which is the same amont of product or more then a lot of my other shampoos. I enjoy the easy snap top which also prevents water from collecting in the lid of the product. I use it everytime i wash my hair since it arrived and while I didn't have dandruff my scalp had been feeling extra irritated and uncomfortable probably because of the very cold weather and product build up. This shampoo fixed it i will definitely be repurchasing.
