Great inspiration here. It’ll be fun to see what you end up with.
Regarding product, I think it’s very individual what works and doesn’t. I’ve tried products that others love but they just don’t work for me. I currently use a mousse or “air dry cream” by OGX. They seem to work well for me but I do find that my hair is unpredictable. And I liked LUS hair gel but it didn’t hold the curl for me. Yours looks curlier than mine so maybe that wouldn’t be an issue.
I also don’t wash every day but I do totally wet it in the shower every morning and style. If I don’t it feels flat all day.
Good luck!
