do 4 year old girls have hairy pussies

No, typically girls do not have "hairy" genitals at the age of 4. Pubic hair usually begins to grow during puberty, which occurs between the ages of 8 and 13 for most girls. Every person's body develops at a different pace, so it is possible for a 4 year old girl to have minimal amounts of pubic hair, but it is not common or expected. If a 4 year old girl does have noticeable hair in her genital area, it could be a sign of a hormonal imbalance and should be discussed with a pediatrician.
