Braids on fine hair?

I’m mixed and I have a weird hair type, it’s really fine, frizzy, and I have 3a-3b curls. I never learned how to manage it, I’ve tried so many products but I can never get it to look good, it really kills my confidence. I’m considering doing braids but because my hair is fine I’m worried about getting traction alopecia, is there a certain type of braid I can do that won’t cause damage? I’d like to add extensions too but I feel like that might be pushing it too far, pls let me know tyy
