Upkeeping your passion twists comes down to three things: the type of hair you decide to use, moisturizing, and good sleep habits. Textured hair is the easiest to both install and detangle, and comes off very natural (via Jorie Hair). When you're working with passion twists, it's important to stick with beauty products that are moisturizing and light — such as a leave-in conditioner spray — to prevent your own hair from drying out or being damaged (via Byrdie).
You should also invest in hair oils to keep your scalp hydrated, but avoid nasty buildup by regularly washing your scalp. Just be careful around your actual twists, and slowly shampoo them so your hairstyle doesn't get ruined (via Jorie Hair). To really stretch out your protective hairstyle, do not neglect your night-time routine. Keep your hair wrapped and protected in a satin or silk sleeping cap — or sleep on a satin pillowcase — to reduce your chances of waking up with frizzy hair (via Byrdie).
