On 21 March 2025, Water Henna by Ons Co., Ltd. was broadcast on Public Home Shopping.
The programme featured the set of Henna Oil, Henna Essence, Indigo Oil and Indigo Essence. It also demonstrated how the product is used: the oil and the essence are stirred together for about a minute, applied to the hair, and left for thirty minutes each.
Water Henna is a natural hair colourant that reformulates henna — until then available only as a powder — as a ready-to-use liquid kit. It has completed the functional-cosmetics review of the Ministry of Food and Drug Safety (No. 20230026680), and the underlying technology is registered as Korean Patent No. 10-2836178, "Natural hair-dye kit based on henna and indigo, method for its manufacture, and hair-dyeing method using the same."
