My hair straightener completely loses its shape on rainy days... Is there a way to make it last longer?

It's been raining again these past few days....

Whenever it rains, all the hard work I put into straightening my hair in the morning goes to waste.

My bangs, in particular, were fine until I left the house,
Whenever I go outside and walk just a little, I get completely drained and go back to my old self. 😭

I looked it up and found that on humid days, hair is affected by moisture in the air.
I heard that even styles created with a curling iron can easily come undone.

How do you keep your bangs styled with a curling iron on rainy days?

I dry my hair completely, then use a curling iron on my bangs, and
I usually spray a little hairspray at the end, but it seems like the curl doesn't last long on rainy days.

Especially when using a hair iron on humid days like the rainy season Fixer or hairspray Does writing it separately definitely help?

Do you have any tips for keeping your hair iron lasting longer on humid days?

I heard there are various methods, such as letting the hair cool completely after using a curling iron or using hairspray.
The method that was most effective when I actually tried it I'm curious about this!

If anyone keeps their bangs curled or styled with a curling iron for a long time even on rainy days, please share your method or product recommendations 🥹
