Yes, I realize Liv Tyler has a perfectly normal hairline. Many people have short, fine hairs that dust their forehead. However, I just don't like looking at it because it makes a beautiful woman appear to be balding.
Short layers in front (that don't get pulled back into a ponytail) can be used to disguise this kind of hairline. You can also use a light styling cream like Sebastian Shaper, Smoothing Groomer to slick back the baby hairs.
