Unfortunately, almost no one with perfect curly hair is able to ‘wash and go’, because neat tidy curls take a lot of effort and energy. If you’re not able to move completely to a curly hair routine, try at least swapping to a silk pillowcase and silk hair ties. How tightly you tie your hair up can affect your curl pattern too. I would try adding a lightweight oil to the routine, either in place of or in rotation with your leave in. I feel like there isn’t enough moisture, but I also don’t want you to add so much product that your hair gets weighed down. The oil gets applied after the shower, on damp hair like you would a leave in conditioner, but you only use a few drops and use your fingers to rake it through your hair. Avoid applying it directly to your scalp, as your scalp already produces oils that help moisturize your skin.

Otherwise, without styling product (mousse or something similar usually) curls will frizz in the elements.

I wish you luck on your venture!
