Get ready, you guys, because we’re about to announce our third (third!!) annual Summer Hair Challenge, in which we ask you to forgo leave-ins and heat for a day and then send us a snap from your phone.

You can take a look at our two previous galleries of product-free, air-dried hair here and here to see what we’re talking about. Last year we got well over 100 photos sent to us, and we were over the moon. This year we want even more, so consider this your early mental-preparation warning.

Couple things:

First, we’re not against using leave-ins as long as they’re clean (and if they’re not clean, we’re not against that either—do your thing!) but we have a dorky maxim about cosmetics in general that goes like this: “More products, more problems.”

What we mean by that is, most conventional products—and especially ones for hair—create problems even as they try to “fix” others, which then necessitates more products. Think of silicone-based leave-ins that coat the hair, then need to be stripped off with harsh shampoo, which then requires a fistful of conditioner, a defrizzer, and maybe a finishing gloss, too.

Second, we’re not against heat styling, either. When it’s cold out, I use heat almost every single day. Whenever I can get away with it, though, I leave my hair alone, and here’s why: When I first started doing this regularly, I didn’t even recognize my own hair. Here’s what I said at the time:

I used to wake up, hop in the shower, use Garnier Fructis Sleek and Shine shampoo and conditioner, or if I was feeling rich I’d use Rene Furterer’s stuff. Then I’d load Phytodefrisant onto my wet hair, and once blow-dried (and sometimes also ironed), I would use one or two finishing serums that probably had silicone or some other garbage in it.

My hair looked how I wanted it to look, but do the math: That’s expensive, and a pain. I was also unwittingly exposing myself to 11 of the 20 ingredients on the Black List in our book—daily. (For more on what’s in shampoo, check this out.)

Anyway, eventually I realized the unmanageable nature of my hair was squarely the fault of the products I was using, and when I made the switch, my hair chilled out.

So that was neat.

But this challenge isn’t really about all that. It isn’t about what’s bad or what’s good. The reason we like the Summer Hair Challenge so much is in part seeing pictures of all of you, but also hearing your stories. Some people had gone years without knowing what their hair looked like air-dried. How cool is it that they tried? And for those of you who do this every day, God bless! We’re going to want your pictures, too.

So in preparation, we want to know: Do you use leave-ins every day? What about heat? And how excited (or pissed) will you be when we ask you to stop both for a day? Have at it.
