Being a hairstylist, it's important to give knowledge to clients on how to keep their hair healthy. From my experience, the more you take time to explain why you're recommending something, the better! So, here's a tad of information that hopefully helps you out!
I have clients who come every two months and I have some that come once a year for a haircut/ trim, and many times people ask the question "How long is long enough to go in between cuts"? First off, not everyone is going to have to come as often as others. It's important to ask yourself what exactly your hair goals are. For most ladies nowadays they want the Long, Beach wave, lived in hair with lots of brightness, (yes - lots of bleaching ) so most of the time this means they only want to take off what's necessary. Unfortunately, when you bleach your hair, if you don't take good care of it at home, your porous ends are going to need a good few inches taken off next visit to the salon. Since The lived in look (aka roots) are popular it means less trips into the salon, - some people go 6 months to a year before they get their balayage redone! So for those light and bright lovers I'd say roughly every 3 months you should get a trim (1/4 inch-1 inch). Then you have the people who have a shorter style like a bob for example, or a pixie. Of course, if you're maintaining a shorter cut you may need to come in every 6 to 8 weeks, some every 24 weeks, it all depends on how fast your hair grows. As for those growing their hair out that don't put any harsh chemicals (bleach, perms, sun in spray,lots of heat), you should ask yourself "On average how much heat do I use on my hair a week?" Do you use it often, seldom, or rarely? The more heat the more split ends which means more frequent haircuts. If you use heat every day maybe every 3 months a trim (again, 1/4 inch- 1 Inch). Rarely users- I would say every 6 months would be fine, and those seldom users are somewhere in the middle of 4-5 months. The clients who see me every 5 weeks for color/root retouch , I usually tell them every third visit we should add a trim in there. This is why trimming when you need to is important, what can happen is you get split ends and the hair strand just keeps splitting up the hair strand. The more the use of heat, chemicals, etc the hair becomes scraggly and damaged, so if you wait a whole year you might need to end up cutting off 5+ inches of damaged hair just from split ends that split halfway up the hair strand and Long hair it out just became short. Don't let your spilt ends split too far; every three months means only four times a year, that's not that bad and you get to keep your long hair while keeping it healthy, sounds like a win to me! I hope this helps you figure out how often you should see your stylist!
