Stage 4

Stage 5

The stage 1 preadolescent has no pubic hair except for a fine "peach fuzz" body hair. 

In stage 2, there is sparse growth of long, slightly darkened, downy hair mostly along the labia.  This hair is usually straight or only slightly curled. 

In stage 3, the pubic hair becomes darker, coarser, and curlier.  It now grows sparsely over the mons veneris area. 

In stage 4, the hair grows in more densely. It becomes as coarse and curly as in the adult, but there is not as much of it. 

The mature adult, stage 5, has the classic coarse and curly pubic hair that extends onto the inner thighs. 
 

 
The final amount, color, and distribution of pubic hair surrounding the vagina is quite variable.  About 90% of woman aged 18 and older have a "horizontal" pattern diagrammed below (far left).  Other hair patterns are also depicted.
