When adding volume to your hair

I've tried buying all sorts of things, but when I got a perm this time, my hairdresser said that hair fixing pins are convenient for both shaping the waves and adding volume to the roots, so I ran to Olive Young and bought these. They are definitely much more convenient, and I'm using them well for both purposes. Since they only cost 2,000 won, the value for money speaks for itself. As long as you let them cool properly, they last a long time.
