Unless you're blessed with Ryan Gosling–esque hair that perfectly parts with just a flip of the head, chances are your mane needs some help. From unruly flyaways to perspiration-activated curls to frizzy, 'fro-like explosions (think Justin Timberlake without a blow-dryer), whatever your problem, there are solutions. "You can embrace your messy hair—it looks sexy—but having the right products and techniques will keep it looking styled," says Kyle Krieger of the Chris McMillan Salon in Beverly Hills, who handles an extensive celebrity clientele. Don't just reach for the clippers, he adds: "A buzz cut isn't always the answer." Follow Krieger's tips and you'll be able to coax your strands into submission.

THE CUT: For the most control, guys with tight ringlets should keep locks under an inch and a half, while those with waves can ask the stylist to point-cut two-to-three-inch layers for added texture. Get your hair cut while it's wet, but note that after it's dried, another quick trim will be necessary, since curls can look a lot different after washing.
GO-TO PRODUCT: A moisturizing cream that controls volume, like Kérastase Nutritive Crème Oléo-Curl ($42; kerastase-usa.com).
STYLIST TIP: Skip the brush. "Twist pieces into place using your fingers instead," Krieger says.

THE CUT: Thinning shears can take up to 50 percent of the weight out of hair while keeping the length. Since mid-length styles often stick straight up, go either short (around an inch and a half) or long to weigh strands down.
GO-TO PRODUCT: Shu Uemura's Shape Paste Sculpting Putty, a medium-hold paste that adds definition ($38; shuuemuraartofhair-usa.com).
STYLIST TIP: Lock in moisture to avoid unwanted pouf. "Brush hair in the evening to disperse natural oils throughout your hair or supplement with jojoba oil," Krieger says.

Justin Timberlake

THE CUT: Make sure the stylist uses scissors—a razor adds texture, which you don't need more of. "Keep hair short on the sides for polish and play with length on top," Krieger says.
GO-TO PRODUCT: Try Oribe Supershine Light Moisturizing Cream, a leave-in conditioner that won't weigh hair down ($49; oribe.com).
STYLIST TIP: Cotton pillowcases (even with a really tight weave) tend to absorb moisture and can rough up hair cuticles during the night, leaving you frizzy in the morning. Opt for a silk pillowcase, which eliminates friction.

Andy Samberg

THE CUT: Frizziness is more of a condition than a texture, so follow the rules for whatever category you fall under—but get your hair cut more frequently. Don't go longer than four to six weeks between trims, since split ends are the primary cause of frizz.
GO-TO PRODUCT: Humidity-blocking Living Proof No Frizz Nourishing Styling Cream ($36; livingproof.com).
STYLIST TIP: "Squeeze hair softly with an old cotton T-shirt when getting out of the shower," Krieger says. Terrycloth towels absorb too much moisture, and vigorous rubbing frays hair cuticles.

When Only a Blow-Dryer Will Do: A Primer

Justin Timberlake's wild days are, seemingly, behind him. He's married, and gone is his kinky, curly hair. The secret to his new grown-up, slick do, says Krieger: wind power. Apply a styling moisturizer (try Aveda Men Pure-formance Grooming Cream, $22; aveda.com), then grab a flat paddle brush and pull hair straight and taut, following closely with the dryer up to six times per section. Start at the back and sides of the head and work your way up to the top. Finish with a smoothing product, like Murray's Superior Hair Dressing Pomade ($3; murrayspomade.com).
