I started using Ryo when I was teaching in Korea. I have fine hair which is past my hips. I also wear my hair in a ponytail nearly everyday. The scent took a bit of getting used to, but I like what it does with my hair. I tried using Kerastase products, but always hated how my hair felt after using the shampoo and conditioner (always felt dry, no matter what I used). So, switched back to Ryo. My hair doesn’t feel brittle. My ends are smoothed. My flyaways have reduced. And, I personally love the smell.
