Waves keep falling out- help?

Hi all, I tried posting this I'm r/wavyhair but it was removed and I don't know why.

I recently worked out that my hair is not straight and frizzy; it's fine with a 2a wave. I've been trying a slightly adapted CGM and my waves look great while still wet, but after air drying they start to fall out fairly rapidly. My hair is about an inch longer than my shoulders and needs a cut, as the bottom couple of inches have bleach damage. I cover my hair for spiritual reasons when I go out, usually with a satin headscarf.

It would be great to get some advice on what I could try to encourage my waves to stay please!

I am in New Zealand so please bear this in mind when recommending products - many of the ones I see recommended often are not available here.

Haircare routine: - Wash with Hask Curl Care Shampoo & conditioner (squish/scrunch conditioner in) - Detangle with a Lady Jayne brush for fine wavy hair while conditioner is in - Schwarzkopf protein treatment a couple of times a week (can't recall exact product name) - Plop with microfibre hair towel for about 5 mins - Microplop if needed before removing hair towel - Scrunch in Hask Curl Creme (I have tried this step with gel, mousse, gel after curl creme, & mousse after curl creme - best results are with curl creme only) - Air dry (I don't have a hair dryer so can't use a diffuser to dry)
