Can’t stop cutting hair- now too short

I used to do this… with cuts and colour every time I felt uneasy; stressed; unsatisfied; ill at ease; restless. I also used to pull out my hair when stressed too.
I think what might be helpful to do, if you can, is to pause the next time you have the urge to change it and see if you can tap into a recognise what the feeling is… how are you feeling just before that urge? If you can do that a couple of times then you can see if there is a bit of a pattern in terms of the feeling that leads to it. From there, you may be able to think about an alternative thing you could do instead.
as others have said, you might want to think this through in therapy too
also for me I made a rule that I was not to do anything to my hair in between hairdressers… I’m quite stubborn so it worked! And I imagined my beloved niece doing what I was doing to her hair
good luck

I did this years ago. It was horrific and j wonder why I was so obsessed. What helped was finding a good hairdresser who could sort it then leave it. It took years to get over it and when I look at photos from that time I'm horrified. I would try.cbt perhaps.

it's hair
it will grow again

I also do this, but it’s only now that I’m feeling better mentally that I recognise what it was.

I used to go for a pixie chop or harsh short bob which never suited me but was sort of act of desperation, as though I could shed layers of something.

I’m with the person suggesting therapy to try and sort out your why.

For now, don’t stress and own it - it’s a part of your journey and you can be positive from this moment on. We are all more than our hair.

Put the scissors down and get to a hairdresser to fix. It might also be worth some therapy to address the deeper issues with why you cut your hair when stressed, it sounds like compulsive behaviour.

Don't do anything else to it yourself! At that length you can't hide errors!

Get yourself to a hairdresser, having googled first to find short haircuts you can show them for inspiration
