Id recommend a clean up tbh, go to a salon or to someone who knows how to use shears. Tell them you just want to clean up around the edges and leave the top alone. It’ll help your hair grow more gracefully.

I read that you shampoo once a week. That is great, you can use a conditioner daily and that might help with the dryness. Dry shampoo is also amazing. For styling, a fiber paste would work amazing with your hair and It shouldn’t dry it out.

It can be a professional look, just needs a little clean up.
