The Eastern philosophy describes the energy of the sky as Yul (律) and that of the ground as Ryo (呂). Hair is Yul and the scalp is Ryo, the ground for hair. Ryo is a hair care brand with the belief that a healthy scalp is the key to youthful, luxuriant, silky and healthy hair. Ryo brings the scalp back to its best possible condition. Vitality through harmony - that’s what Yulryo (律呂) is.
