I'm afraid that in DS's case the first couple of haircuts brought about the end of the curls. As a baby he had this amazing curly red/auburn head of hair, it was almost an afro it was so full on. He had his first hair cut at 7 months (and one every couple of months from then on in) and by the time he was 1 the curls were long gone. But his hair also changed colour, to more of a brown with red highlights. And now, it's turning blonde.
