• I trim my bangs myself every couple of weeks because I like them at a very precise length — just below the eyebrows and above the lashes — the hair then gets gradually longer toward the sides of my face. I hold my scissors vertically and make tiny, irregular snips, following a gentle curve.

• Because they sit against your forehead, bangs tend to get greasier than the rest of your hair. Most days, I just wash my fringe instead of my whole head — it takes seconds and makes a huge difference. I love Biologique Recherche’s Shampooing VIP O2 and, if I’m in a rush, Bumble and Bumble’s Prêt-à-Powder Dry Shampoo Mist.
• For straighter hair types, getting layers and keeping some pieces chin-length means your fringe will blend in seamlessly as it grows. I get my hair cut professionally every two to three months. When my bangs have grown out, I place my La Bonne Brosse hairbrush underneath that section and blow-dry upward from below, to lift at the root and make them appear shorter.

• Never wet, flatten or pull your hair taut before cutting a fringe. Whatever your texture, you’ll end up with bangs an inch or two shorter than intended. Instead, gently comb the bangs in the direction they naturally fall — I like using a Denman D12 comb — and clip the rest of your hair out of the way. With sharp scissors (such as Tweezerman’s Stainless 2000 shears), snip upward into the ends. The biggest mistake people make is trying to achieve a perfect blunt line, which is almost impossible to do on yourself.

• For curly hair, style your hair as you normally would, whether with a cream or oil — I like Pattern Beauty’s Curl Gel. Then, use your fingers to coil small sections, for definition. Only then should you cut, working curl by curl.

• Injecting volume into your bangs is one of the best ways to fake a fresh cut. I love a large Velcro roller — very ’80s. Start by blow-drying your fringe (Parlux makes brilliant dryers for minimal frizz), using your fingers to brush the hair forward. Then pull that section upward, place the roller underneath the ends and roll it backward so it’s pulled away from the forehead. Blast the hair with heat for a few minutes and let it cool completely for about 20 minutes before removing the roller.
• Greasy bangs are always an issue backstage at fashion shows. One of the quickest fixes is running a Hair by Sam McKnight Lazy Girl Biodegradable Hair Cleanse Cloth through the fringe. Unlike dry shampoo — which can end up pushing oil around the scalp — it actually cleans the hair with ingredients like witch hazel, aloe vera and alcohol, leaving it slightly damp so you can quickly redry and restyle.

• I have very fine hair, so I rely on products that add texture. GermanOhr’s Volume Spray works wonders and gives my bangs that slightly lived-in look. After shooting in Stockholm last summer, I also became obsessed with Swedish products, like Happy Crazy Mine’s Bounce Bounce Curl Activator Mist.
• A tip I picked up on set is to dry bangs from side to side. Once I’ve washed and quickly brushed my hair, I attach a nozzle to my Dyson Supersonic and start by drying the hair with downward strokes. Then I hold the blow dryer steady above my bangs, angled downward, and push my bangs to the left and then the right, for a slightly messy finish.
• My grandma used to shake a little baby powder onto her bangs to freshen them up. When I haven’t had time to wash my hair, I do the same — it’s gentle on the hair and surprisingly effective. When I’m at home relaxing, if my bangs have grown out, I’ll pin them back with bobby pins or pull them up with an elastic band. My forehead needs to breathe!
