I was concerned about my hair's tendency to get frizzy, so I used Kerastase Orange every day. However, the amount of Kerastase in the bottle was getting smaller and smaller, and I felt that daily use wasn't very cost-effective, so I bought this oil to switch to a more convenient oil every two days. As a result, my hair became more manageable and smoother than Kerastase Orange, as I use the entire Melty series of shampoos and conditioners. If I still feel the same way after using up the whole bottle, I plan to stop using Kerastase and use this oil every day.
