MOGAM Changpo Root Ritual Scalp Serum — Korean Scalp Serum for Itchy, Dry Scalp | CYoung Tester Program

A leave-on scalp serum for people whose scalp itches because it is dry. Shampoo is rinsed off in about 60 seconds. A dry, tight scalp needs care that stays on — the way you would never treat dry facial skin with cleanser alone. This serum is applied directly to the scalp and left on, morning and night. The first ingredient is not water but changpo root water. Changpo (Acorus gramineus, sweet flag) is the root Koreans have used to wash their hair every Dano festival for centuries. Changpo-derived content makes up 51.8% of the formula (520,415 ppm), supported by houttuynia cordata, green tea and perilla leaf. In a human application test (CBRC-H-260429-44, Cutis Bio Research Center, Seoul) with 22 adult women using the product twice daily for 2 weeks, scalp redness decreased 84.2%, scalp flaking 77.9% and itching 54.9%, with skin hydration up 48.3% (p<0.05). All 22 participants improved on redness, flaking and itching. Human patch test result: 0.03, non-irritating. Individual results vary. Formulated without alcohol, menthol, synthetic fragrance or synthetic colorant, so it can be used every day on a sensitive scalp. It dries clean without residue and does not weigh hair down.

How to use

Part your hair and apply directly to the scalp, section by section. Massage lightly with your fingertips until absorbed. No rinsing needed. Use twice a day, morning and night, on a dry scalp. Style as usual.

MOGAM

Korean scalp skincare for itchy, dry scalp — rooted in the changpo (sweet flag) ritual

Dongui MOGAM is a Korean scalp skincare brand focused solely on 'scalp itchiness'. Its name is derived from 『Donguibogam』, a medical book from the Joseon Dynasty. Korea has a long-standing tradition of washing hair with boiled calamus water on Dano day to clarify the scalp, and we've brought that tradition back to modern scalp care. Our signature product, the Calamus Scalp Serum, features Acorus Calamus Root Water as its primary ingredient, not purified water, and contains Calamus, Houttuynia Cordata, Green Tea, and Centella Asiatica to manage itchiness, redness, and flakes together. Our products are developed with the consultation of a specialist in Korean Medicine Otorhinolaryngology, Dermatology, and Ophthalmology. In a third-party human application test (22 adult women, 2 weeks), improvements were confirmed: scalp soothing (redness) by 84.2%, flakes by 77.9%, and itchiness by 54.9%. All 22 participants showed improvement in soothing, flakes, and itchiness, and a patch test on 32 individuals with sensitive skin resulted in a low irritation index of 0.03. Its transparent, water-type formula, free from alcohol, menthol, and synthetic fragrances, ensures daily use won't burden the scalp. We believe the scalp should be cared for like facial skin. We are creating a routine that spans washing (shampoo), post-wash (serum), and moments of itchiness (ampoule). Our customers are those who experience itchiness due to seborrheic scalp, post-dye irritation, or lifestyle habits that cover the scalp for extended periods, such as hijabs or braids. Within five months of its launch in Korea, over 1,100 reviews have accumulated, and now we aim to share the same experience with itchy scalps worldwide.
