New Moon, Full Moon and Haircutting

Q: When is the best time to cut your hair to help it grow faster - new moon or full moon - or every 6 to 8 weeks as you may have stated?
A: In order to keep your hair healthy and growing as long as possible, you need to keep the ends trimmed of split ends and damage. That doesn’t mean that you MUST cut off “X-amount” of hair every “Y-number” of weeks. It simply means that you should examine the hair regularly and take action to correct problems as they begin to become apparent.
The Old Wives’ Tale about cutting the hair at the new moon (or full moon, depending on where in the country you are) simply stemmed from the convenient “Calendar Markers” of the moon’s phases to remind people to keep up certain grooming habits. Since the moon is “new” or “full” every four weeks, then the hair would be cut once a month. Traditionally, the entire family (or at least all the men) would get haircuts on the same day for the sake of expedience.

Today, since haircuts (even trims) are much more costly and salon visits often require scheduling, the 6-8 week time frame comes into play as a means of keeping customers aware of the need to come back to the salon, without seeming to be simply trying to get as much money as possible from the client.
The bottom line is that you need to look at matters from an intensely personal perspective. If your hair is prone to split ends, you need to have it trimmed and treated more frequently than someone whose hair is healthy and smooth from root to tip. If cost is a consideration, share that with your stylist. I’m sure he or she will be willing to try and work out a schedule with you that will help you achieve your goals.
