I have an earlier answer that might interest you! I've bolded the parts most relevant to your question:

• Were medieval women as hairless as the movies show it? When did women start to shave?

~~

The Internet loves women's hygiene badhistory almost as much as it loves food badhistory, and what to my knowledge is the major scholarly article on body hair in the Middle Ages takes nearly all its evidence about women from the sixteenth century.

That said, for the later Middle Ages, removal of women's body hair--especially pubic hair--is amply discussed in two types of sources: medical texts and satire. That probably means some if not many Western women, or at least middle/upper class women, sought to remove body hair. It definitely suggests there was some discomfort in talking about the idea.

Medieval art and literature make it clear that body hair was primarily a sexual symbol, associated as it biologically is with puberty. Male beauty was strongly tied to youth. For women, things were more complicated. Public hair/body hair did continue to represent unbridled sexuality, and thus, lack of hair its restraint.

But--so did its removal. Erasmus' Moriae Encomium (Praise of Folly) counts among its fools old women who prepare for their sexual exploits by tweezing their pubic hairs. The implication in that paragraph, particularly as paired with the immediately preceding enumeration of the follies of randy old men, is that they take this action to try to recapture their youthful, sexual days.

Erasmus is of course writing satire, as are his contemporaries who ridicule prostitutes for trimming or completely removing The Hair Down There. That makes it hard to say how widespread a practice depilation actually was, on its own. But the common strand among the texts points to a deeply entrenched cultural value on pubic hair/pubic hair removal.

Medical texts from the later Middle Ages offer another set of evidence for the practice of hair removal, although again, the connection between medical texts and actual practice is...frequently contentious. An extra wrinkle here is the importance of Greek and Arabic influence on the later Latin (and through that, the western vernaculars) medical tradition.

Both ancient Greece and the contemporary Islamic world practiced depilation, which is where the social pressure for depilation makes its way back into the western European mainstream. But the emphasis is slightly different in the Islamic and Christian worlds.

In medieval Islam, which is how the tradition of depilation makes its way back into Europe (clothing fashion, hair fashion, and hygiene-type rituals like steam baths were a major point of cultural interaction in the Crusader states), body hair removal was associated with other practices to ensure bodily purity--nail trimming, mustache and beard grooming, circumcision. So in the medieval Islamic world, there is definitely a sense of spiritual cleanliness to the practice.

Christian writing from western Europe, on the other hand, tends to emphasize the aesthetic aspects of depilation, usually with a sexualized angle (the facade of youth, ergo sexual desirability--the common denominator in Latin medieval descriptions of Beautiful People is youth).

One really interesting piece of evidence is one of the texts in the Trotula, De ornatu mulierum (On Women's Adornment). The Trotula is a group of 12th century texts that medieval writers attributed to a female medical practitioner and author named Trota; Monica Green argues persuasively that "Trota" or another woman did indeed write at least some of the texts and that her influence can be detected behind them all.

De ornatu mulierum discusses depilation in quite a bit of depth--methods, the influence of "Saracen women" on the western practice, and so forth. It's important to note that depilation is THE FIRST subject discussed by this text. Straight off:

In order that a woman might become very soft and smooth and without hairs from her head down...

Most of the methods are a non-wax version of waxing (quicklime is a common ingredient). And then, because the Trotula is awesome, it goes on to discuss the medieval equivalent of how to heal razor burn. (...Egg whites. No, for real.)

Oh, and after you wax, you should take a nap. :)

Later medical authors reiterate similar depilatory methods. A subsequent text that claims to be "from Trota" (but is clearly not) includes them alongside what we might see as more "medical" cures and information. And Henri de Mondeville, the early 14th century French surgeon, has quite a lot to say in his Surgery about women removing body hair!

He reports that women like to remove all the hair below their heads. While he is quick to say he disapproves, he is equally sure that medical practitioners must be involved or must at least give advice in order that they do it as safely as possible.

Much like the humor/satire writers discussed above, Henri explicitly connects hair removal with the restoration of youth and an attempt to cast a false air of chastity.

Which would only be a factor if the woman were going out to have sex, of course.
