How do you turn a dolls hair white?

To turn a doll's hair white, you can use a fabric dye or a hair dye specifically designed for synthetic fibers, following the manufacturer's instructions. Alternatively, you can try using a mixture of water and bleach, but be cautious as this can damage the hair if not done carefully. For a safer option, consider using a white spray paint made for plastics, applying it lightly to avoid clumping. Always test on a small area first to ensure the desired effect.
