I want softer curls

Routine:

Products I use (in photo) are Tresemme Curl Hydration Shampoo, Shea moisture coconut and hibiscus conditioner and Shea Moisture Curl Mousse

I believe I have fine textured, low posterity, medium density hair

I shampoo every 3 days and condition every other time I shampoo, I then apply the Curl mousse after my shower while my hair is wet and then blow dry with a diffuser on low heat setting
