To take your hair salon DIY, we consulted celebrity hairstylist and Biolage brand ambassador Sunnie Brook for insider tips on how to trim your hair at home. For curly hair, you might want to proceed with caution and see how the curls bounce back up before going back in with your scissors. Remember: You can always cut more, but you can’t glue your curls back on, says Brook. With wavy tresses herself, Brook just trims her ends with the scissors pointing toward her (be careful of your fingers!) in two sections—one on each side. It doesn’t have to be perfect, especially if you want more of a tousled look. Rather, if you’re partial to a straight, blunt edge, feel free to cut straight across. Even if the line isn’t completely straight, “you can always point cut the edge to soften it,” Brook says. Again, you want to start out with dry hair. Brook says to blow dry clean hair using a dense boar brush, keeping your hold light and airy. (You don’t want a lot of tension, she says). Next, the trim. To decipher where your bangs should end, Brook says to use the high points of your brow as a guide (you want the bangs to fall just there). Create clean, triangle sections and pull back the rest of the hair you don’t want to cut with a clip. Then within that triangle section, create even smaller sections of half an inch or less (precision is key here). Then trim each section to your desired length, using the first section you did as a guide. Either keep the blunt edge if that’s your jam, or feel free to point cut into the bang to create a softer line. “If you want to create a ‘curtain bang’ or shag bang,” Brook adds, “point cut into the very middle of the bang. This will make the middle go short to long.” And if you’ve quite literally butchered the haircut? “Have a glass of wine, a good laugh, and watch some styling videos on YouTube,” Brook says. “Remember, your haircut is not a tattoo! It will grow out!” She mentions it may also be a great time to experiment with new styles (read: styles, not cuts) like waves or curls; after all, a slightly crooked edge can easily hide within a tousled fringe; call it quarantine’s “bed-head chic.”
