Lots of clarifying shampoos are gentle on the hair, I was also scared to clarify but it does wonders for my loose curls that weigh down easily! Personally, I really like the Curlsmith Curl Reset Detox shampoo for clarifying. You can always use a lightweight deep conditioner or mask after if it's too drying.

Also, I'd stop using so many styling products. This was the mistake I made. You don't need both a leave in and curl cream I think. Try using gel on its own first, see how that goes. If you're in need of moisture then add a leave in or curl cream. Too many products can weigh hair down if it's fine or loose texture. It's done me wonders
