Yeah it's tricky being low porosity, but not course. My crown is very fine and sometimes it loses curl. It seems to be once every 3 months. I certainly don't need lots of protein regularly.
I looked, the filler has aloe in it. Everything has aloe in it
Oat protein works a bit different than other proteins. It doesn't concentrate itself on the cuticle, if I'm understanding this correctly.
Hydrolyzed Oat Protein - Derived from oats; adds texture and thickens hair, soothes, softens, and nourishes it. Restores strength and elasticity. Easily diffuses into the hair shaft to give a fuller, healthier look.
I might look for DT with oat and milk protein. I think if I did regular DT with my DB it would help. I'm the lazy DT person EVER.
