Jessica or similar doll wig ; a short baby cut with small ringlet curls around the sides and neck.
These modacrylic wig are good quality.  Modacrylic fiber is manageable and easy to style.  The style can be changed by using a dab shampoo with cold water, a quality conditioner in the cold water rinse and reset with regular curlers or perm rods.  The fiber is heat resistant up to 200 Fahrenheit; it can be air dried and carefully styled with electric "hot rollers" or curling iron. The wig will return to its original style if washed, combed out and allowed to air dry. 
The hair may also be cut like human hair
