How to keep hair from getting frizzy?

To keep hair from getting frizzy, especially overnight, here's a condensed summary of the techniques and strategies from the provided search results:

1. Hair oil for overnight maintenance: Apply a few drops of hair oil (e.g., honey-infused or with antioxidants) to damp or dry hair for frizz control and shine.
2. Deep hydration: Use leave-in conditioners and hair masks to maintain moisture, which combats frizz from dry hair.
3. Smooth with heat: After styling with a round brush and blow dryer, use a cool shot option on the hair dryer to set the style and lock in moisture.
4. Gentle brushing and combing: Use wide-toothed combs and soft bristle brushes to minimize damage and frizz.
5. Microfiber towels: Dry hair with microfiber towels to absorb the most water, reducing the risk of heat damage and frizz.
6. Leave-in treatments: Use lightweight leave-in treatments, such as those with antioxidants and fatty acids, to nourish hair.
7. Friendly hairspray: Spray a light, non-sticky hairspray onto a brush or comb to tame frizz.
8. Anti-frizz serums: Use serums containing ingredients like Dimethiconol that help realign hair fibers and provide a smooth texture.
9. Silk pillowcases: Swap out cotton pillowcases for silk to reduce friction and maintain smoothness.
10. Stylish haircare tools: Use ionic hairdryers or air-drying techniques for less frizz and reduced damage.
11. Preventing "bedhead" frizz: Avoid contact between hair strands and the pillowcase; try a nighttime hair wrap or create a high bun and sleep on a silk pillowcase.
12. Embrace natural hair texture: Accept and work with your natural hair texture, especially in humid conditions.
13. Adjust heat styling: Lightly mist hair with water before styling to reintroduce moisture and reduce frizz.
14. Trim regularly: Maintain a neat trim every 6-8 weeks to reduce split ends, which contribute to frizziness.
15. Keep hands off: Avoid playing with hair during styling, which can increase frizz.

These tips and techniques will help you maintain smooth, frizz-free hair overnight and beyond.
