Most married man can attest that generally speaking, a woman spends a great deal of effort on her hair. Today is nothing like the past, however. In the 1770s, especially in France and England, women of means took to extravagant hairstyles. It was commonplace in that day for women to wear their hair (naturally or with a wig) stacked up to 4 feet high (1.2 meters).
Cork or fabric cushions called toques were shaped like a heart or spear, and then real or fake hair was curled, waved, or frizzed over the pillow. The hair was then dusted with wheat flour and decorated with all sorts of trinkets like feathers, stuffed birds, bird cages, plates of fruit, even wooden ship models. Sometimes the additions to the hair were to commemorate special events, like the launching of a hot air balloon, the sailing of a ship, or the vaccination of a person.
To keep her appearance at the best, women would sometimes don these hairstyles for days or weeks at a time.
The most pleasant looking, attractively adorned woman, however, might also have the most awful of attitudes. People may write songs about her incomparable beauty, but living with her is an altogether different turn of the worm.
Personally, my wife is beautiful however she does her hair. This is not sexist; it is the recognition of the unique and distinct beauty God has placed in women. The Bible recognizes this beauty, but also instructs women:
Do not let your beauty be that outward adorning of arranging the hair, of wearing gold, or of putting on fine apparel; but let it be the hidden person of the heart, with the incorruptible ornament of a gentle and quiet spirit, which is very precious in the sight of God (1 Peter 3:3-4).
