The key to this cut is having enough length on top to create some height in the pomp. Tell your barber to take the sides down short (though not buzzed) and leave enough hair up top so you can execute the hard side part and comb the front up and back for some height. Better yet, just bring in a picture of old Harvey.
To get Harvey’s subdued shine and strong hold, you’ll need a gel that’s low on goop and flakiness and high on strength of hold. Experiment until you find the one that’s right for you, but we recommend Imperial Gel Pomade, TOWELDRY’s Gel Styler, or Number 4 Firm Hold Hair Gel. If you want the hold and the height without the glare, try Baxter of California's Clay Pomade. In either case, depending on how much your hair naturally takes to going vertical, you might also need a bit of hairspray like the Ojon volume advance™ Volumizing Styling Spray to top it off.
After showering and shampooing, do a light towel dry. Warm up a small amount of gel in your hands and run through your hair from the roots lifting upwards. Then, using a blow dryer set to low heat, lift and dry the hair in the front while combing upwards with a comb. The longer you blowdry the front, the more volume you’ll get. After blowdrying, apply more gel throughout hair with your hands and use your comb to cut the sidepart and gently sculpt front hair up and back. To stick the landing, top the whole thing off with a quick spritz of hair spray.
