No it is not possible. But it is possible to over wash hair until the point where it is dry and brittle. Depending on your hair type it is recommended to wash with shampoo only every other day and if you have African American hair every three to four days on average.
NO! this will ruin your dolls hair if you really have to send her to the doll hospital where they can take care of her hair and she will be as good as new
It is possible.
Dolls hair can't grow.
You could brush it with a soft newborn baby hair brush to keep it knot free but don't wash it because that might damage it.
Hair dryers made it possible for people to wash their hair and dry it before they go out, meaning that they don't have go out with wet hair.
No it will destroy the dolls hair, maybe make it fall out
