It's regressive because of the marginal utility of money. The difference between earning 0 and 10K (getting to pay rent and groceries) is more important than the difference between earning 100K and 110K (better luxuries), yet a flat tax assigns it the same value.
Also, by definition a flat tax is neither progressive nor regressive. , so I'm pretty confused about what you're talking about. Note, flat doesn't mean fair by everyone's definition.
