Hi. Another protein sensitive fine haired curly here. I typically buy protein free products but there are 2 gels that I like that have protein in them so I rotate them but I don't use protein everytime I style and I never PT. If I use a poo or conditioner that has protein in it plus layer a protein gel, thats definitely too much for me so my advice is find 1 or 2 products that contain some protein and throw them in the mix every now and then.

You can also try a mild protein conditioner to use every now and then that you rinse out. This didn't work for me since I like leaving conditioner in my hair and protein conditioners turn my hair straw like very quickly. I did better with protein stylers (mind you the protein is not really high up on list and not considered protein rich). Hope this makes sense!

Like BS/ACV rinses, limit protein/humectants.
