Recommendation for a lightweight hair serum

This is a great hair serum for repairing damaged hair and calming dry, frizzy hair. It is the Migu Hara Daily Silk Effect Hair Serum, and unlike heavy hair oils, it has a light texture, so I use it frequently. As expected of a serum, it has a slightly viscous consistency, but it doesn't feel sticky when applied to the hair. It nourishes the hair with protein ingredients, giving it a noticeable shine, so I use it well every day.
