Have you ever wondered why *certain* parts of ur body has curly curly hair despite ur own head of hair being straight?

Yes… I’m toking abt *ahem* pubic hair.

Hey, it’s perfectly normal to be curious you know. =p Besides, the inspiration for this particular post is from a family-oriented tv show on channel 8 in SG. Heh.

So, why is pubic hair curly???

Let’s talk about hair.

Hair is made of a protein called keratin, the stuff of horse hooves, antlers and fingernails. There are two types of hair: vellus, which is our fine body hair; and terminal, which is the coarser hair on our scalps, eyebrows, pubic areas, and men’s faces, chests and limbs.

Terminal hairs grow faster than vellus hairs. Terminal hairs are sometimes curly because they can sprout from an oval-shaped follicle, rather than a round one.

Hair type and shape is determined by the shape of the follicle – the flatter the follicle, the curlier the hair. During adolescence, the androgens (male sex hormones) floating around your body instruct all the follicles in your pubic area to grow flat, thus becoming curly-hair follicles.

The follicles on your head aren’t usually sensitive to androgens, so curly head-hair is the result of genetic predisposition.
