@yourbesthair: Straightening with NO product? Smooth in a SERUM first ✅ Straightening dry, bare hair is how you end up with frizz and flyaways. Warm a little serum between your palms, smooth it through the lengths, and then straighten. The iron glides more easily and the finish comes out sleek and shiny. Save this one for your next straightening day. After 35 years of doing hair, I never pick up the iron without it.
