The longest pubic hair, is recorded to have reached below the knee of woman. British physician and human sexuality researcher Havelock Ellis (1859–1939) wrote:

The pubic hair of women is usually shorter than that of men, [..] In a series of 100 women attended during confinement in London and the north of England I have only once (in a rather blonde Lancashire woman) found the hair on labia reaching a conspicuous length of several inches and forming an obstruction to the manipulations involved in delivery.

But Jahn delivered a woman whose pubic hair was longer than that of her head, reaching below her knee; Paulini also knew a woman whose pubic hair nearly reached her knees and was sold to make wigs; Bartholin mentions a soldier’s wife who plaited her pubic hair behind her back; while Brantôme has several references to abnormally long hair in ladies of the French court during the sixteenth century. In 8 cases out of 2200 Bergh found the pubic hair forming a large curly wig extending to the iliac spines. The individual hairs have occasionally been found so stiff and brush-like as to render coitus difficult.

Hair stylist Roberta Muccinelli produced a viral campaign for the razor manufacturer Remington, featuring models with very long merkins (pubic hair wigs).
