What is the ruling on a wife neglecting her personal hygiene and not attending to her husband's conjugal rights, and does the husband come to dislike her in this situation? And what should he do?

A wife must obey her husband concerning his enjoyment of her, in terms of cleanliness and removing anything that might be off-putting, such as hair, dirt, long nails, and bad odors. Likewise, she is not permitted to prevent her husband from enjoying her. The husband should be gentle with his wife when commanding or advising her. As for divorce, it only takes effect through utterance, even if the wife does not hear it.
