I had hardly no hair until I was 2 as well, my son had tons of hair by 1 so I knew my poor daughter was going to be like me and she is, poor girl has hardly no hair at all it will come! It’s probably for the best right now keep their little heads cool in the hot Texas summer
My sister daughter hair ain’t grow in till she was almost two some kids just take time, I also seen pple shave baby head as a culture thing
