My daughter is a competition dancer and I have learned a lot about hair pieces. Originally I had no idea that many of the hair styles the girls had were not really their own hair, but an additional piece or wig that they were wearing. I found a wonderful company that sells all of these hair extensions and hair wigs called Divatress. They offer a huge selection of wigs and hair care products. Many professional stylists shop here but so can you!
Usually we put her hair in to a bun, which I have become an expert at and then put a hair piece over it. For example when the girls have long pony tails this is usually a hair piece for all the girls to look the same. Here is an example of one of the pony tails. Lauren has had several lengths for different routines. Especially hip hop routines.
So many dancers wear human hair wig or hair extensions. Lauren also wore one like this with lots of curls. It looked gorgeous in and even better for me I didn't have to spend hours curling her hair with a curling iron or putting it up in curlers.
As someone who is challenged doing hair styles this is an awesome option for me. All of their hair pieces come in a variety of colors so you can make sure it matches your daughter's hair. You should definitely check them out!
