When growing your hair, the last thing you want to do is go to the hairdresser and have it cut; ironically, trimming your hair more every six to eight weeks will help it grow faster. If you want your hair to be long, thick, and strong, you should consult your hairdresser about creating a regular trimming schedule based on your hair type, per Good Housekeeping.
The main problem with not getting your hair cut regularly is split ends. Meri Kate O'Connor, a senior colorist and educator at Eva Scrivo Salon in New York City, says, "When the split goes up the hair shaft, it becomes so thin that it breaks." In addition, the longer you wait between cuts, the more your hair is susceptible to breakage, which is detrimental to hair growth because "once you split your hair, there's no way to repair it," O'Connor told Good Housekeeping.
Unmanageable hair and split or sticky ends are signs that your hair needs a trim, but it's best not to wait for these. "Truthfully, it is best to give your hair a trim before these signs because once you see them, there is already damage done," Philip B, a celebrity hair treatment expert, told Good House Keeping.
