Will Hair Regrow When Skin Does from the Cut On My Head?

I fell and have a tiny sliver 1/4 inch scar, but a i lost a chunk of hair and thin layer of skin about the size of a quarter. Will hair regrow when the skin does? how long?

If you lost hair bearing skin, then hair will not grow back. If the skin is sutured skin edge to skin edge (hair-to-hair edge), it will grow back.
