  • Apply Neuro Protect HeatCTRL® Iron Hairspray to dry hair for thermal protection.
  • To ensure the smoothest finish and greatest control, smooth only a small amount of hair on each pass, and move the tool slowly and steadily.
  • Run a fine-tooth comb through the hair ahead of the iron to get the hair distributed evenly on the iron’s surface.
  • To smooth: begin approximately 1-2 inches from the scalp on the first pass, then move closer to the scalp on the second pass.
  • To flip or wave: close the iron over the hair at the place where you wish the wave to begin and rotate the tool 180 degrees. With firm tension, slowly pull the iron through the hair clockwise all the way through the ends.
  • To set your look, spray hair with Neuro Protect HeatCTRL® Iron Hairspray.
