Need support before i give up - restarting curly hair

Somehow over the years my hair has just gotten more and more curlier - and since the last 2 years I have been blow drying them. 

I restarted managing my curls and below you can find the products I use but here are my main questions and concerns:

\\- I stopped the curly girl method because I hated the feeling of product on my hair. If you can suggest products in Germany that are lighter and feel better I would appreciate it 

\\- I have always been confused about my curl type and how healthy curls look

\\- How can I do a low maintenance curl method! I don’t need the perfect curls but something that just looks tidy and well kept. I am not very patient so I struggle sometimes 

Routine:    
Shampoo     
I change up between different ones and I regularly use a shampoo for hard water (maybe 1 in 10 days) since Germany has hard water    
Currently I am using John Freida and a Sensitive scalp shampoo from Balea

Conditioner    
Banana Hair Food by garnier     
Tsubaki Hair Mask 

Leave in    
Kerastase Curl Manifesto     
I have tried Cantu and others but I hate how it feels on my hair. Makes greasy clumps and weighs them down 

Serum    
L’Oréal Heat Protectant 

I have not used a gel in almost 3 years because of the texture it leaves my hair in 

I have been blowdrying and hence I felt my hair were healthy but if I don’t then it looks like in the pictures.     
Diffusing - I diffused my hair in the first 4 pictures and the last few are the next day. 

Any help or advice is helpful! I am open to trying new things and new products.     
I am based in Germany but am Indian
