"As you're reaching four months since your last haircut, you'll notice that the top layer is starting to get flat," Fowler says. Volumizing products will help keep your hair from looking sad and droopy.

You're still going to have to rely on styling to keep your hair looking great. Hair masks can help hydrate your dry ends, says Reyman. He also advises turning up the heat on your styling tools. Counterintuitive as it may seem, it's better to style a section of hair once on a higher heat setting than many times on a lower setting.

Even if you've followed this advice to a T, your ends are going to look dry. To combat it, mist a shine spray on your ends to keep your hair looking "alive," says Fowler. (We like Kevin Murphy Shimmer Shine.) Just be sure to keep it concentrated on the ends if you have fine hair, otherwise it will add weight and make your hair look greasy.

At the end of the month, enjoy your (hard-earned) haircut.
