Ryo Double Effector Black Shampoo boosts hair strength and darkens greying hair with revolutionary Black Toning Technology. After three weeks of use, it reduces hair loss by 79.8%. The shampoo's natural ingredients, including Ginseng, Ginger, Camellia, and Soybean, fortify the scalp. With daily application, it conceals grey hair for a superior, natural darkening effect. Clinical testing proves that its use won't irritate sensitive scalps or eyes, and all skin types can use it safely. Dermatologists approve its effectiveness without any animal product.

Q & A

Q. How much should I use to be effective?
A. It is recommended to use it at least 21 times. However, depending on the individual’s hair condition, the result may vary.

Q. Can it crosswise with other regular shampoo?
A. It is recommended to use the product steadily until it changes gray hair to a satisfactory hair color. After your gray hair gets dark enough, you can use it two to three times a week with other shampoos.

Q. Don’t your hands get stained?
A. Although some pigments may temporarily remain on rough surfaces such as calluses, dead skin cells, rough nails and others, you can remove it easily by using soap or body wash.
