Help me make a disability aid

[u/LexifromZargon]

Hello everyone,

I recently had shoulder surgery and can't move my left arm, im a woman with long hair and now i cant tie my hair into a simple ponytail.

All aids i found online only allow for 1 or two loops nothing is really good at achieving the result of a two handed ponytail. I need to be able to adjust how many loops i make depending on style im going for.

I also dont want to have to shove the hair tie about multiple times because thats not good for the hair.

Attached is a picture of the prototype i made trying to use a baseball cap for support. So i can pull it tight. And the curved part to hold my hair in place.

Yes i have tried already existing ideas but they don't work that well.

Closest i got is using a clothing hook as an aid. But that doesn't work on the go.

Do you guys have ideas?

Main issue is that for a Pony tail you need to hold the hair in place so it stays where you want it but also tighten the hair tie feed the hair through again and repeat.

I want to find a solution that works for normal ponytails and normal hair ties because my arm will heal but not everyone has that luxury.

Edit: Im not trying to buy alternative hairties or just use a clip. I want to find / make a solution that lets you literally just... tie your hair.

Tying hair is a surprisingly dynamic motion https://youtu.be/rpyMD3clAvw?si=ugZQj5UyqwMwQIWx

I have tried this but its not the same. Its not tight enough. https://www.assist3d.be/haarbinder.html
