We'll admit it's not always easy to tell when you need a haircut, or if it can wait another week or so.
But if your hair checks any of the following four boxes, it may be time to take care of it.
And when you do, make sure you're getting the best haircut possible.
1. You're getting tired of taming it in the morning.
Fighting with your hair to stay straight every morning is a hassle you just don't need when you're getting ready for work.
And if you're attacking it with tons of product every morning to get it to stay in place, or it requires maintenance throughout the day, it might be time to get a trim.
2. A friend or significant other says, "Wow, your hair is getting long."
Ah, the universal way of saying "your hair looks terrible" politely. If someone else has noticed it — especially someone you don't see very often — it may be time for a trip to the barber relatively soon.
Trust me, it's not quite the compliment you're interpreting it as.
3. You notice you're looking scraggly.
You know the signs: wavy hair turning to curls around your neck, the Bieber swoop, hair over your ears, or unruly sideburns. It's hard to look neat and well-groomed when you have this going on, so give it a fix by a professional.
4. Your intended style has faded away.
If you're trying to maintain a particular hairstyle, like a fade, you need to get a haircut pretty regularly. When you notice the style you're going for has faded away, it's time to head back to the barber for a touch-up or a new 'do.
If all of this is too much trouble, just go every month or so. It can't hurt.
