About RYO
RYO (려) is a Korean hair and scalp care brand from Amorepacific. According to Amorepacific, it launched in 2008 and draws on the group’s scalp research, which dates back to 1973. The brand’s idea is “Root Your Own beauty”: care that starts at the scalp and the root of the hair, for full, healthy-looking hair.

How to build a RYO routine
Wash with a shampoo that suits your scalp, then apply a scalp tonic or serum on a clean scalp. Follow with a treatment or conditioner on the lengths, and finish with a leave-in such as the Root:Gen Hair Volume Filler. Try a new product on a small area first and follow the directions on the label.
