Getting a haircut is a great way to change your style. Some people grow out their hair starting in the fall and will get regular trims thru the winter, then in the spring they cut it short for a fresh new cut. Changing your haircut can be as simple as adding face framing or cutting your bangs.
Regular trims are a must, no matter the style you wear. You should get a trim every 4-6 weeks. Short hair usually requires it getting cut every 4 weeks, where a long hairstyle can usually go 6 weeks.
