I cut my own fringe and it wasn't a total disaster
A few days ago I was overcome with what I was sure would be a regrettable impulse. It was nearly New Year's eve and I wanted a change. Specifically a change to my hair. So, acting against my better judgement and ignoring the stern voice in my head yelling something along the lines of 'this is literally something people do in bad romcoms. This is one of those things that goes horribly wrong every single time anyone anywhere does it' I grabbed a pair of totally unsuitable scissors from the cutlery drawer and chopped myself a fringe over the bathroom sink.
The punchline of all this is that I love it. Trust me, I am just as surprised as you. I've been incredibly boring with my hair for most of my life, opting to stick with a side-swept fringe and long wavy locks combo for the entirety of my teens and twenties, but something didn't feel right about it any more. As I've got older I've started to want more of a definitive look, rather than just a haircut. That, and my growing suspicion that the whole do was starting to look just a little too 2007.
What I aimed for was a kind of choppy, long, messy fringe which could be swept to both sides 60s-style, and which would draw attention to my eyes and work better with my go-to feline liquid liner. And, much to my own surprise, that's what I ended up with.
And now for some unsolicited advice:
Things to consider when ill-advisedly cutting one's own fringe
Consider your hair type
I have naturally wavy hair with a wiry texture which holds a style like nobody's business, so mistakes and mishaps are easier for me to cover up than for someone with poker straight glossy locks wher every misplaced hair is immediately apparent. If you have hair that is less forgiving, consider calling in a professional.
Be aware that it might go super wrong
Make peace with the idea that you might screw it up and have stupid looking hair for a bit. My hair grows bizarrely fast so I'm in the lucky position of not having to live with my mistakes for too long. If your hair is slow to grow, think very carefully before snipping. I have also had some kind of fringe setup for years, and am used to trimming my own hair, so I know I at least have some experience.
Use a picture for reference
You don't have to copy someone else's style exactly, but it helps to at least know what you're aiming for. I screen grabbed a few images of Emma Stone at her rock-n-roll fringey best and used those to keep myself on track.
take it incredibly, excruciatingly slowly
You can always cut more off, but it takes an age to grow it back. There is no downside to taking tonnes of time over this kind of thing. I even did a few changes on subsequent days after the initial chop. For example when I realised a couple of millimetres shorter would suit my face shape more, or that I needed to thin out the ends to get a more piecey texture. Sometimes you have to live in a hairstyle for a bit to really know what you want from it, so go slow and expect to do a few revisions.
If you've never had a fringe before, go to a hairdresser
Seriously, it's not worth it. I went from a long, side-swept fringe to a short, blunt fringe. All I had to do was take some length off what I already had and add some I-have-no-idea-what-I'm-doing-but-this-seems-sort-of-right layery bits around my face to compliment my newly symmetrical look. If you're starting from nothing the chances that it will look weird af are exponentially higher. Pay someone who knows what they are doing to help you.
