2b/2c Losing Curls :(

in Hair Type 2
Hello! I'm relatively new to naturally curly, and I'm looking for help on my curl regimen.
I have shoulder length, thick/coarse 2b/2c hair with low/medium porosity that gets weighed down very easily. I'd been successfully styling my hair with Organix shampoo and conditioner with Paul Mitchell flexible hold styling mousse for years, and over the past year my hair has been getting limp and losing its curl, and not clumping as well as it used to. I tried the Kinky Curly line for a while and there really wasn't much change.
I'm not sure if I just need to invest in a good deep conditioner or treatment, change my styling product, or my entire routine. I've been trying to do research on all this and I'm just getting frustrated, there's so many products out there! Just looking for any advice to get my curls back, I miss them!

2b/2c - f - iii - low porosity - normal elasticity
Holy Grail: Matrix Biolage Cleansing Conditioner for Curly Hair
I rotate through the rest of my products depending on weather and etc but usually don't need them
I try not to use products tested on animals if I can help it.
