Britt Lower’s Husband Kenna Kennor Shares the Science of Dry Shampoo and How Not to Overdo It

If you’ve ever overslept, dashed out the door, or just had “nope, not today” energy toward washing your hair, you already know the magic of dry shampoo. And if you’ve ever wondered how celebrities bounce from red carpet to morning talk show without a greasy hair day in sight—yeah, this little spray can is their secret too. Kenna Kennor, an A-list hairstylist and Britt Lower’s husband, has thoughts about how dry shampoo really works and how to use it like a pro.

What’s Actually in Dry Shampoo?

Let’s kick this off: dry shampoo is usually a powder (some sprays, some loose), packed with starches—think rice, corn, or even clay. These star ingredients are oil magnets. They soak up the extra grease and gunk sitting on your roots, so hair looks (and feels) cleaner. Some versions throw in a little fragrance for a just-washed illusion and a hint of texture to perk up limp, flattened hair.

Imagine blotting paper for your face, but for your scalp.

How Does It Actually Work? A Quick Science Fix

Here’s the fun part: when you spray or sprinkle the product onto your roots, the powder particles latch onto oil, sweat, and even leftover styling product. After a minute or two, a quick massage and good brush-through pulls up the oil-soaked powder, leaving you with fresher, revived strands on days when a shampoo is just not happening.

But Kenna warns that it’s a great stand-in, not a replacement. Eventually, sweat and skin cells build up, and you’ll need a real wash.

Kenna’s No-Fail Tips for Maximum Freshness

  1. Section, Don’t Spray Blindly Kenna likes to separate hair into sections, then hit only the greasy spots. This way, you avoid that chalky, dull look.
  2. Let It Sit The biggest mistake Kenna spots? Spraying and immediately rubbing in. Give it a minute or two. Let the powder do its job before you work it through.
  3. Massage and Brush—Both Matter For even absorption, Kenna massages the product in with his fingertips (think scalp scratch, not frantic rub). Then, use a brush to really sweep out any excess—especially if you’re brunette.
  4. Don’t Go Overboard Dry shampoo is clutch for so many, but Kenna reminds even his celeb clients not to pile it on day after day. Too much can clog your scalp, leave behind residue, and even cause breakouts. Give your hair a true wash every two or three days, depending on your routine and hair type.

Bonus Use: Add Some Oomph Planning on a quick updo, messy bun, or need a little grip for braids? Kenna swears a shot of dry shampoo gives thin, slippery hair just the right texture for styles with staying power.

Bottom Line? Use It Wisely and Rock That Second (or Third) Day Hair

Dry shampoo isn’t magic, but when you know the science—and have Kenna Kennor’s tricks in your back pocket—you’ll breeze through those lazy days with confidence. Happy styling! Because great hair days don’t always require effort, just smart products and timing.
