When you've found a hairstyle you love, it can end up becoming your signature look - a haircut you stick with for months, years or even decades in some cases. To keep your hair looking just so, you need to get regular trims - but why do you need them and how regular should they be?
Why get a trim
Firstly, trims remove split and broken ends which is great for overall hair health. Secondly, trims help to maintain the shape of your hair, restoring it to the same dimensions as when you got the haircut in the first place. In a similar vein, trims are essential for avoiding any awkward angles when growing your hair out.
When to get a trim
The frequency of your trims all depends on the haircut you have. On average, hair grows at a rate of half an inch per month. For some cuts, this won't make a huge difference, but for others like the undercut, it can throw your whole style completely out of whack.
For short cuts, every 4-6 weeks is the general recommendation. If you need parts of your head shaved, you will most likely have to get this done more often, roughly twice per month or more often if your hair grows really fast - there isn't really a one-size-fits-all rule.
For longer styles, you can go every 6-8 weeks as the small amount of growth in that time is less likely change the way your hair acts with your normal styling routine.
Play it by ear
If these time slots don't really work for you, a good way to tell if you should get a trim or not is by looking at how your hair behaves. If it's not behaving at all and you have no idea why, it's probably because the hair is just a fraction too long.
