You may have heard that one of the positive side effects of pregnancy is that gorgeous, thick, full head of hair. Well, it’s a positive if you are normally of the limp-haired variety, anyway. Then you simply adore that the pregnant scalp tends to jealously retain every fiber, leading to all-out lovely locks.

Then, about three months post-partum, those fabulous filaments start appearing on your sweater. And in dinner. And in diapers. And on that one spot on your back you just can’t reach. And don’t even get me started on the drain.

Not only is your marvelous mane now diminishing at an alarming rate, but you can no longer set your infant on the carpet without first administering some sort of hairball preventative medication.

Your shower time lengthens as shampooing consumes most of your morning simply in vain effort of finding an end to the squandering of your sensational strands.

You eventually give up, and it’s good that you do. Because as soon as you pick up that brush, whatever remains of your tantalizing tresses leaps so willingly from your thatch to those bristles that you might get a little suspicious.

And suddenly, you start to sympathize with Britney Spears.

So that’s why she did it.
