Nope, esp not like 3b. Maybe try braiding it down while its damp n when u take it down, tie it down for a while? That won't really loosen them but will tame em and also cut down on tangles.
If u really want permanently loosen curls, texlax. I did it to my hair and it made it a little looser (I say a little becuz I still wanted the volume of my hair so I didn't leave it in long enough to fully process). It doesn't lay down though, cuz that's not what I wanted,but that's a route u can go.
That's asking a lot of ur hair, to basically become a different curl pattern with just some styling products.
