What is a way to loosen my curls without damaging them too much?
You can brush them with a round soft brush, take a hair strand or a curl and twisted in the curl's direction with the brush, do it when dry. It will loose the curls without breaking them. Give it a try :)
If they are long enough you can do a "banana bun" or french twist type thing with a big clip. It loosens the curl without flattening it completely.
