1 Corinthians 11:3 But I would have you know, that the head of every man is Christ; and the head of the woman is the man; and the head of Christ is God.
1 Corinthians 11:4 Every man praying or prophesying, having his head covered, dishonoureth his head.
1 Corinthians 11:5 But every woman that prayeth or prophesieth with her head uncovered dishonoureth her head: for that is even all one as if she were shaven.
1 Corinthians 11:6 For if the woman be not covered, let her also be shorn: but if it be a shame for a woman to be shorn or shaven, let her be covered.

If this is just about hair cutting, why is verse 3 so careful about identifying exactly what the heads are that need to be uncovered and those that need to be covered?
