No shade to Marie Claire's own Lauren Valenti, who sleeps on one like the goddamn princess she is. No shade to anyone who rests her head on a silk pillowcase every night, because it really does make a difference in the quality of your skin and hair. All I'm saying is that, depending on what you want in life/beauty, you might not need to switch.
Why? Because one simply cannot get hair like this sleeping on natural protein fibers derived from insect larvae.
I understand that smooth, even-textured hair is the ideal. I want that too—sometimes. But the other 98 percent of the time—because of my aesthetic and unwillingness to brush or wield a blowdryer or apparently condition enough, even though the amount I use could be described as a "sh*tload"—I want Caroline de Maigret's stringy-soft, perpetually rumpled, irregular waves. And I have them...when I "revert" to a regular old cotton pillowcase.
Just like a dye job or dry shampoo, friction can be your friend if you're after a drier effect or "sexture," a term stylist Kat Zemtsova coined in reference to après-roll-in-the-hay bedhead. It may not be so great for preventing roughness and fray-age, but whatever—it's my look, my way.
At the same time, though, I'm not about to give up my Slipsilk Pillowcase, especially when I'm after the gelato-swirl, highly polished hair Nabil Harlow of Balmain Hair Couture creates. (And, you know, when my ends start to feel like the comb's dragging through sand, as another stylist put it recently. 😭)
In the end, it's not really about *needing* a silk pillowcase or any special equipment, really—it's about getting what you want by any *means* you want. Freedom of choice, get you a girl who can do both, etc., etc.—with liberty and good hair for all.
