Two things...die polishing takes away design elements from the field first which reduces the overall profile of the design elements, to include the outline of the hair. This may make two coins from the same year appear to have different lengths of hair.
Second, the design used is changed every few years, which may change the appearance of the hair somewhat.
One thing to understand is that the same engraving - the same design - is used throughout any given year. Two coins that look different from the same year look that way because the dies were polished, altered, or the coins were struck softly - not because of design changes.
