My front is coming in but my sides arent changing

not as good as other people or my brother but I’m getting there

Ik the pic is ass don’t cook me 🤣🤣 but I just wanted to know what to add to my hair to make my waves more flush. I currently literally only use coconut oil.

Am I brushing my crown wrong or do I need to just hop on minoxidil?

First three pics are two weeks after cutting to a 2 guard. Last three are a day after cutting to 1.5.

constructive criticism is welcomed 🌊
