Always one to top new year's resolutions. Get into shape. There's not a lot of time to workout these days. We're trying to juggle so much. And abc's becky worley found out a way to make your lunch workout a possibility, with what you do afterwards. Dry shampoos and going back to the office? Reporter: One hour to work out and make it back to the office. One problem -- washing and drying my hair takes about 25 minutes. So, do you think the boss would let me have a two-hour lunch break? No. When I read online that you can skip the gym wash by using dry shampoo, sprays that remove oil from the roots of your hair, i had to dry. Step one, get sweaty. Sports club l.A. Lots of ways to do that. Mission accomplished. I'm pouring with sweat, including my roots. Now, for the big test. Rinse off the sweat. No hair wash. Just a one-minute blowout to get the sweat off the roots. Now, for dry shampoo. I tried a bunch of these at home. And they seemed to work equally. They absorb oil from the roots. But their intended use is to let a blowout work for days. But using it as a workout pick-me-up is another story. This is an offlabel use, advised by bloggers online. We'll see if it works. Hold eight inches away. Spray liberally. Shake it out. And give it a few minutes as you freshen up the rest of your look. It looks pretty freshly shampooed, if you is ask me. This is what my hair looked like before. And this is the after-gym dry shampoo look. Nobody at the office will know how sweaty I was just five minutes ago. Added bonus -- my hair smells pretty good. For "good morning america," becky worley, abc news, san francisco. Yes. Becky always looks stunning for us. Why did you put them all in front of me? You were so inquisitive. I'm inquisitive. I'm a believer in these bad boys. Without a doubt. Proof. Are you okay? Proof that the hair actually moves. We're in the middle of an experiment here. I use these at the gym or between washes. I'm feeling cleaner. Are you feeling fresh? It will change your life. Yeah. It has changed my life.
