What is the way to deal with a wife who does not care for her appearance and personal hygiene despite repeated warnings, and is the solution in marrying another or divorce?

A wife must obey her husband in everything related to his enjoyment of her, such as her cleanliness, beautification, and adorning herself for him in a way that pleases him. The husband is advised to explain this to his wife with wisdom and good counsel, to be gentle with her, and to remember the hadith: "No believing man should hate a believing woman," and the hadith: "Woman was created from a rib." Divorce is not advised; rather, continued guidance and counsel are recommended.
