Leo Bancroft with Handbag demonstrates how to straighten your hair with a hair straightener. First, use good clips to section off your hair. Fasten the clip to your hair in a straight line and then fold the excess hair up. Comb through the hair to ensure that you are not straightening any knots. Apply the flat iron to the hair without using a clamping motion. Gently glide the hair straightener over the hair shaft with the comb or brush guiding the hair straightener through the hair. Using these techniques will ensure that you get perfectly straightened, salon style hair without much fuss.
