These extensions are really good quality. I'm just not sure about the grams. Says 220 grams but doesn't feel like it. It feels less. I've had luxy hair extensions same grams previous to these and though the quality was lesser, in my opinion the grams felt like way thicker. I dont have super thick hair either so I wasn't worried but I have to maneouvr them in my head just right for them to look good. They are very good quality though, super shiney and don't have a tangle issue like many other brands do. Overall I'd say I'm happy.
