The science says “no” but the experience says otherwise. While it’s hard to argue with the science of hair growth it certainly seems as though cutting or shaving hair regularly does cause it to grow back both faster and fuller. The fact is however that it doesn’t matter. That’s right, it doesn’t matter if cutting hair causes it to grow back faster or not. You can’t have tree roots extending from your nostrils and expect to have much success in the modern world whether in business or personal affairs. So if hairs extending from your nose have become an issue (as they will with most guys eventually) man up and trim them back whether or not this trimming is going to cause accelerated growth. Not doing so is just gross.\r
