In this video, we learn how to flat iron your American Girl doll's hair. First, heat up your flat iron on the lowest heat setting it has. Now, brush your doll's hair so it doesn't have any lumps or bumps in it. Clip the to of the hair up and then take a small section from the bottom of the head. Then, squirt some water on the hair until it's wet. Comb through the hair and then run the flat iron through the hair very quickly. Run it through again if needed, then continue on to other sections in the hair. When finished, comb through again and the hair will look great!
