Can the Carlotta wig or any of the Global wigs be brushed and styled by a child?

This wig can be brushed, very carefully. Most little ones are not patient enough to take the time to start brushing from the bottom up and slowly so as to avoid making tangles. It can be braided but since the wig is made of synthetic fibers, the curls would need to be heat treated to change from curly to straight or to add curls. So to answer your question, while this wig (and most Global wigs) can be brushed and restyled, it would be too difficult for a child to do.
