This is one of the most common questions I hear as a hair stylist. I do believe it is a misunderstood statement resulting in different answers. I am here to clarify for you!
"Does cutting my hair make it grow faster?" The answer is No. Your hair will not grow faster. There is no vein running up into the scalp yelling, "Hey! We've got a trim over here! Let's pick up the pace!" =) It will get longer faster if you let your stylist know you are growing it out. He/She may have you come in every 6-8 weeks for a blunt trim at the ends of your hair. This will keep your ends looking fuller and from getting split ends.
So the question is, "If I keep my hair trimmed regularly will it get longer faster?" The answer is Yes. Your ends will no longer split causing you to have to trim more hair off at your next visit. The results are longer healthier hair! Also, while growing your hair out please eat plenty of protein and take a multi vitamin. Multi Vitamins make you sick? Take it after eating a good sized meal with some carbs. You may still feel sick after a salad but the carbs should keep you from the side effects.
