Acrylic paint
can give a Barbie some funky hair dye colors.
Barbie dolls are made with nylon or saran synthetic fiber hair. You can dye the hair using an acrylic paint wash, but synthetic doll hair doesn't take dye the way human hair does. A Barbie with thick strands of nylon hair will take acrylic paint better than dolls with thin strands. Use a blonde Barbie for best results.
Instructions
1. Squeeze a dime-sized amount of acrylic paint in a paper cup.
2. Mix water into the paint one teaspoon at a time. Stir until the dye is the consistency of watery ink. It may take several teaspoons to achieve this.
3. Put the Barbie on a rag and fan her hair out away from her body.
4. Dip the flea comb into the dye and carefully comb it through the hair. Cover all the roots and ends, but don't get any dye on the face or body. The dye will stain the plastic.
5. Place the Barbie upside down to dry. It may take more than a day for the hair to dry completely. Comb the hair once or twice a day while it's drying to prevent it from getting stiff.
