That hairs may fall, and none grow again.and:
A dipilitory whereby a hairy place is made bald.which leave you wondering exactly what they are talking about, because they only mention hairy places in general. Did people back then want bald heads? However this entry, which seems at first to be about something else, makes what they are talking about perfectly clear:
That Children may never have Beards.--From Eighteen books of the secrets of art and nature--
That Boys and Girls may never have hair grow on their secrets [vaginas] or beards, annoint the privities [privates]...
Why were they interested in depilatating their genitalia? The asumptions I would make from a modern perspective might include:
1. From being exposed to nude sculptures/paintings depicting people with such attributes.
2. Because they were exposed to many sexual partners and/or found it sexually enticing.
3. Health concerns (lice).
Obviously, these recipes may have been intended for professionals, not the general population, or they may have been oddities meant to provide insight into medicine. But considering how the author talked about breast and vaginal restoration in this book, I'm going with my second assumption.
